00:00:10in semiconductor

00:00:11in all of that

00:00:13yeah, it's a

00:00:14pure form semiconductor

00:00:16which we can say

00:01:07कंडॉक्सिंट में पाट लेंगे और अगर हमसे बूला जाए जीरो केल्विन पर क्या होगा जीरो केल्विन पर

00:01:14can do it completely completely empty and you can do it with insulator

00:01:21can do it with room temperature 300 Kelvin or 37 degrees Celsius

00:01:26here is the electron here is the electron up again three after vacancy vacancies

00:01:32come on the holes or the hypothetical concept is holes can motion balance

00:02:59लेकिन प्र favour this disease और्फिस एक वार नहीं नकला यह उसी में घूम रहा है trees

00:03:17हो गया जितने एज़ए हो रही हो जैंब एक स्वार्ण ठीयोरी में यह

00:03:22Conduction Band में होता है और इस तेहोरी में यह valence band में होता है

00:03:25लेकिन इस वाली थेहोरी में Tying नाम की चीज़ नहीं होती है

00:03:28क्योंकितो बांड ब्रेक करने वाली थेहोरी है

00:03:30यह कोवलेंट बांड और यह है

00:03:32Energy Band

00:03:34तो यहां पर electron ही आ गया जितने alls उतने ही

00:03:38electrons here we are entirely neutral as well a case my class is about kitty current electricity

00:03:43body your conductivity j equals to sigma iota i equals to an e a video that we take you value

00:03:52me into eota at the current electricity may have mobility electrons can't get ticket

00:03:57connected with the electron and the water tiny bond hotel again semi-conductor me h h

00:04:31energy or the energy degree of the energy mass may convert away obviously the rules when

00:04:37I am come out electron to the other data hope that you have a key bottom of the key

00:04:42I say Sigma Jota is key value add to any new I say and this kind of number of electrons

00:04:49concentration you have a number of electrons per unit volume electron got charge electron

00:04:55of

00:05:00Oh

00:05:02Oh

00:05:07Oh

00:05:16Oh

00:05:19Oh

00:05:21he won't I had a current my donor support care to conductivity where we don't know he support

00:05:27carrying it which is key conductivity and e-view or is key conductivity be an e-view looking at

00:05:34holes key or your electrons key charge okay same at the end this character don't know

00:05:41color it's an old one day take now the data I and I kept a intrinsic concentration do

00:05:48not clear say multiply like ocean

00:06:18I am

00:06:21I am

00:06:23I am

00:06:25I am

00:06:27I am

00:06:29I am

00:06:31Oh

00:06:38Oh

00:06:40Yeah

00:06:42Oh

00:06:44Oh

00:06:46Oh

00:06:48Oh

00:06:50Oh

00:06:52you know real state variable resistance if this setup cushion if this setup is kept at

00:07:08high temperature surrounding

00:07:13if this setup is kept at high temperature surrounding

00:07:22then value of real state

00:07:35dash laga to fill in the blanks for a dash

00:07:40to keep the reading

00:07:41to keep the reading of emitter same

00:07:51decrease

00:07:57किसके लिए पूछ बोल रहे है

00:07:59value of real state

00:08:01उसके आगे dash लिखाया हमने यह

00:08:03कि यहाँ पर क्या आना चाहिए

00:08:05हम चाहते हैं emitter की reading same मनी रहे

00:08:07तो real state की value decrease करने चाहिए

00:08:09increase करने चाहिए

00:08:11same रहने चाहिए

00:08:13कोई matter ही नहीं करता

00:08:15कि अए हमांग

00:09:36Holes

00:09:38Holes

00:09:39Administrative

00:09:40I come home you can say alpha key value negative I tell you about it is moving so it's a current

00:09:48to our friend Joe I have a cup of the oil and our friend come with a guy to current but he got

00:09:53looking to catch at the current same way to maintain I to our equivalent same Rana J or our

00:10:04equivalent same kub rega your are you are to come over us ka for real state ki value increase

00:10:10kardu so if you are my real state ki value increase kardhi to iska resistance jitna

00:10:17kamo go to naiya badao takir aric went where a current where I say you question

00:10:25agar hamarah semiconductor ki zaga metal hota to the way temperature badaanipa resistance

00:10:31One of the options I asked a question is that I have a very strong position in the

00:11:01concentration of electron holes pair

00:11:22concentration of

00:11:27electron holes pair in intrinsic

00:11:33semiconductor and intrinsic

00:11:40semiconductor is 1.072 into 10 to the

00:11:51power 10 per cubic centimeter

00:11:57at 300 Kelvin

00:12:03कि इस लाइन का मतलब कह बहुत बार मिलेंगे ऐसे श्यूषन जाने की एक क्यूबिक

00:12:11संटीमिटर में

00:12:14है इस एनवीन यानि की ट्विन डिज्टी सेवन डिजी सेल्सेस टेंपरेचर पर और

00:12:18फिर्टन उल्स के इतने पेर से यह पेर्स कैसे बने होंगे हो गारमली जनरेटेड क्योंकि यह रूम टैम्परेचर पर कुछ हुआ ही नी था कोई था ही नहीं एक खाली तवर एक भरा हुँआ था लेकिन ट्वेटी से बने हुआए एदर से उधर अधर्वान गए होंगे यह

00:12:48to get to take up a call to reflect from India to a centimeter cube man it's right

00:12:55at a year electron say a whole sir it's really electron say it's a need to keep

00:13:01here it's a whole set in electrons and it's a couple to and I and my love small

00:13:07and my love per centimeter per volume make it my head if mobility of holes and

00:13:13electrons if mobility of holes and electrons

00:13:22are respectively

00:13:26are you

00:13:33are you

00:13:35are some of the camera for a piece of square per world into second

00:13:40and one three five zero centimeters for per world into second value say

00:13:48like a car ordered increasing decreasing my tell him make a hole holes

00:13:54key mobility come or the electrons key job out is the bad while electron

00:13:58has to gather the car

00:14:04at 300 Kelvin

00:14:11then find out conductivity of semiconductor

00:14:48Semiconductor है, conductivity में दो लोग participate करते हैं.

00:15:18Semiconductor है, conductivity में देखने के आदा छोड़ दो, इसे तोड़ी न सीख पाते हैं.

00:15:30वामला देखते हैं, फिर वापस बेल रखेंगे. इस तो सीखें नहीं पाएंगे?

00:15:37Conductivity है, electrons का भी यूज़ होने वाला है, holes का भी यूज़ होने वाला और दोनों add-on ही होंगे.

00:16:01अच्छा, electrons के लिए N e mu, holes के लिए भी N e mu, लेकिन यार, शायद हमें पता है, यह value value तो intrinsic में सेम ही होती है.

00:16:17तो इनमें दोनों को common ही ले लिया, तो अच्छा, चार्ज भी सेम है, तो यह mu e plus mu h अंदर आ जाएगा, अच्छा, N की value दोनों के लिए एक ही तो है, तो इसको double करके मत लगा देना, वो यहाँ लग और यहाँ लग लिखते, फिर common लेते तो भी यही बहारा था.

00:16:31अच्छ, अच्छ, एलेक्ट्रोन का चार्ज, 1.6, 10 to the power minus 19, mobility, एलेक्ट्रोन के लिए 1, 3, 5, 0 और यह 480, कितना आ रहा है, भई?

00:16:483.1, यहाँ रहेगा,

00:16:51माइनस नाइन,

00:17:05मिटर में नहीं कर रहा हूँ मैं,

00:17:06अच्छ, यूनिट देखो, एक मिनिट, अच्छ, आर की वैल्यू, रू, एल, बाय, यह होता है, तो रेजिस्टिविटी, रू, ए, बाय, आर, यह, अच्छ, यह तो ओम आ गया, अच्छ, मेटर स्क्वाइर, और यह मेटर क्या बचेगा, मेटर, यह रेजिस्टिविटी है

00:17:36मेन आय लिया मैने किसमे लिया है, सेंटिमेतर, यह सेंटिमेतर स्कॉائर दिया हुआ है, तो ओम मेन cathया स्कॉइर के करण मेन यह यह सेंटिमेटर मेरने दिया है, अगर किसी का मिटर दिख रहा थो यह, स्कॉर अटेय पना यहार्य एधर टें� all the power minus 4 और रो दे एनाह, ओम आ

00:18:06I am the last class in the covalent bond theory in the room temperature.

00:18:21I am the last class in the covalent bond theory.

00:18:26I am the last class in the covalent bond theory.

00:18:4110 to the power 12 में से एक टूट रहा है और germanium में 10 to the power 9 में से एक ज्यादा किस में टूट रहे हैं?

00:18:5110 to the power 12 में से एक और 10 to the power 9 में से एक तो ज्यादा टूट रहे हैं germanium में क्योंकि germanium में outer electron थोड़ा दूर है इसलिए आराम से थोड़ा फोड़ा जा सकता है.

00:19:07Silicon में 30 वार बेट मैंने बोलो था हर चीज वैल्यू जो जाता आएंगे ना आकड़े वो silicon के लिए जाता आएंगे तो यार 10 to the power 12 में से एक टूट रहा है मालनों silicon के क्रिस्ट का एक मोल का सेंपल है एक मोल में लग बढ़ कितमे 10 to the power 23 अचा 10 to the power 23 है 10 to the power 12 में से एक टूट �

00:19:3711 मतलब एक मोल में 10 to the मतलब एक मोल यानिकी 10 to the power 23 अटम्स के सेंपल में से 10 to the power 11 ही बोन टूट रहे और इतने ही लेक्टन रोल्स बंद रहे होंगे जर्मेनियम में थोड़े से जादा बंद रहे होंगे 10 to the power 9 से डिवाइड होगा 10 to the power 14 मैं से लिकने रेफरेंस लेके चल �

00:20:07अगर मोल लिया 10 to the power 23 अटम हो 10 to the power 23 के जो आउप्र मोस के पूरे के पूरे पूरे एलेक्ट्रोंस होंगे वो सब के सब कंडक्शन में महीं मिलेंगी कि उनके वैलेंस और कंडक्शन में एक दूसरे के साथ और लेट कर रहे हैं तो जो थर्ड और लास और बीट में है ना ल

00:20:37किसी काम के नहीं है उनकी कंडक्टिविटी बहुत काम है कि उसमें टेमपरेचर 27 पर ही यूज करेंगे ऐसा तो है निदो सो तीन सो पर टीवी चलाएंगे लेकिन टीवी को चलाने से पहले गरम नहीं कर पाएंगे वही इसलिए इंट्रिंसिक का यूज नहीं किया जता है �

00:21:07एक्स्ट्रिंसिक सेमिकंड़क्टर के साथ मैं ब्रेकिट में यार वो जो इंट्रिंसिक था उसके साथ मैं कुछ जोड दिया था जिसको हमने नाम दिया था इंपिरिटीज

00:21:23इसमें लिखें

00:23:53but the intrinsic and intrinsic and a pure form silicon color from germanium

00:23:58color from kissy got a cut on camera room temperature for the three-hours

00:24:03when they are put naked the probability of 10 to the power 12 minutes I get 10 to

00:24:10connected to the city and I can't do it I can't do it I can't do it I can't do it

00:24:15I have improved some of the material right with a teacher that currently this

00:24:19click on a number of electrons and number of holes jockey come the conduction

00:24:23my partner will put it there this process of all that I think of your

00:24:27total data current on Google Earth at the event of a fact that I can add

00:24:31current as I make a silicon Joe's a crystal can under I'm new period of

00:24:36market already I got a market out of the silicon can nature the problem of

00:24:40your side current movement there is a barrier to silicon get a freeway at

00:24:44I am a silicon can nature when I write my own limited amount of my head and I took

00:24:50bullet that I got a big concentration can I think is concentration may I must go add

00:24:55career but I think concentration at the one race to 10 to the power six se laker one race

00:25:01to 10 to the power 10 that is come a club here other it may have come to us may a cat

00:25:08in purity come in love yeah the range it may come here those may say it's not impurity will

00:25:16up to see the mark marriage dresser for a chapter of the other means for average

00:25:22bathroom to attend to the power six or ten to the power a pen may say a clear and average

00:25:2810 to the power it may say a process with other amara parts may silicon pure a pure

00:25:36silicon from the bolt in intrinsic oh my lord silicon car take more a take more silicon

00:25:44make it miss silicon get them song a 10 to the power 23 intrinsic man's kit name

00:25:49military 10 to the power 11 electron souls when it is again other on the heart and

00:25:56to the power it silicon atom may it does a impurity ڈال دیا the actual name make

00:26:02it any impurities ڈالی देखो अच्च 10 to the power 8 में एक impurity ڈالी तो एक में

00:26:08कितना डालेंगे इतना अच्च एक मोल में कितना डालेंगे एक मोल किल पर इसे लिखना

00:26:13पड़ेगा कितना आएगा कितना आएगा 10 to the power 50 अरे पर 10 to the power 15

00:26:20एक मोल में जबकि यहां पर कितने एलेक्टों सोल से अब जहां पर 10 to the power 11

00:26:28जब इंट्रेंसिक था तो इंट्रेंसिक में एक मोल जानिके 10 to the power 23

00:26:34एक्टम्स में से 10 to the power 11 ही लेक्टों और होल्स बन रहे थे लेकिन हमने अगर

00:26:40एवरेज कंसेंट्रेशन डाला हर 10 to the power 8 सिलिकन में एक इंपिरूटी डाल दी एक्स्टा तो उससे देखा तो मुझे पता चला एक मोल सिलिकन

00:26:50में 10 to the power 15 एक्स्टा है और अभी आगे जाकर पता चलेगा इंपिरूटी का एक अकेला एटम या तो एक इलेक्ट्रों देता है या फिर एक होल्स देगा में अगर एक

00:27:03एक एक अटम एक एलेक्ट्रों देता हो तो कितने आए हमारे पास इंपिरूटी के 10 to the power 15 तो

00:27:09So, how many electrons are? 10 to the power 15, extra.

00:27:14First, 10 to the power 11, now extra.

00:27:1710 to the power 15, 10 to the power 4, 10,000 times.

00:27:23Conductivity, 10,000 times.

00:27:26This is good for intrinsic comparison.

00:27:29If we have detailed details, then we have talked about it.

00:27:32So, let's take this part.

00:27:39All right.

00:28:01Oh, can you feel like I am a little bit more?

00:28:20I would like to say it.

00:28:27we are

00:28:30here

00:35:05to the power

00:35:0611

00:35:07बहुत कम

00:35:08तो हमने क्या तोड़ फोल मचा दी

00:35:10मान लो यह तोड़ दिया

00:35:11तो यह तोड़ दिया तो यहां पर यह

00:35:13एक electron holes बन गया

00:35:14एक किसी और को तोड़ दो ऐसा करते हैं

00:35:16इसको तोड़ देते हैं

00:35:17तो यहां holes और यह electrons बन गया

00:35:19तो यह वाले जो electrons और holes हैं

00:35:22यह है thermally generated

00:35:25जो हमेश यह तो intrinsic में भी थे हैं

00:35:28intrinsic में भी तोड़ टूटने के करने नो रहे थे

00:35:32तो यहां पर आगए अच्छे यह thermally generated वाले हैं

00:35:35इनमें electrons और holes दोनों का नंबर बराबर है इस वाले में तो

00:35:40लेकिन यार यहां पर पता चला due to impurity

00:35:44due to dropping यहां लिख दिया

00:35:49अन एक्स्ट्रा इलेक्ट्रोन गेवन बाइ

00:36:04कि इम्पिरिटी एटम कि इवन बाइ इम्पिरिटी एटम जो होता है

00:36:20वह एलेक्ट्रोन दे रहा है और जो दे रहा है वह क्या कहलाता है डोनर डोनेट कर रहा हो

00:36:26कर रहो

01:26:56Thank you,
