Electronic Devices Lecture-10: Bonding Forces In solids and Holes in semiconductors

[@deepakpandit893]

Hi sir, i m very lucky to get a teacher like you. Its a blessing for me. Your all videos are very helpful for me as i m preparing from myself.

[@lakshmisrinivasadimulam964]

In the second problem u told conductivity as 8000 but u wrote 800(ohm-cm) -1

[@premlatasinha4031]

sir,can you provide lectures on topics that have been added in ECE ESE exam(technical section) like advanced electronics,advanced communication,basic electrical etc???

[@kiruthikaanbazhagan5004]

sir i think at 8.59 the value of conductivity=8000 and current density is 80A/sq of cm

[@UnacademyFlux]

yaa my mistake..thak you

[@careerkickneet]

Kiruthika Anbazhagan i also agree with u .but It's silly mistakes mainly focussed on concept .

[@abhisheksingh9086]

Please share the link of notes...

[@abhinavkumar322]

sir, i have a confusion when we apply thermal energy then some time we say that electron which is present in valence bond they got enough energy and jump to conduction band and some time we say that covalent bond will broken and then e goes to C.B so my question is that when covalent will broken and when valence e will go to C.B after apply thermal energy

[@UnacademyFlux]

abhinav kumar breaking covalent bond means making a free electron, i.e that electron only goes to conduction band

[@lakshmidhar6277]

hlo sir, in the above lecture u told that as we increase the temperature in semi conductors electron hole pair will be generated ,so without applying potential is it possible to have a current(beacuse electron hole pair generate current )

[@rahulkumpati8313]

No free electrons in nacl means it will be insulator But current passes through salt water know sir??

[@kiruthikaanbazhagan5004]

thanks for your video sir when will you start analog electronics sir?

[@tharunvelamala8959]

#17:17 3p6???

[@naveenreddy5092]

sir when you will upload emf full syllabus ?

[@shilparamisetty7048]

Sir i think dat the electronic Configaration which u hve writen fa Ge is incrrct.. Pls check it..

[@kalakantiabhishek7816]

sir....will you able to be complete the syllabus for 2018

[@UnacademyFlux]

yes but it may go up to October or November as i am concentrated on giving more knowledge rather than simply completing the syllabus

[@kalakantiabhishek7816]

your lectures are superb sir thanx a lot for that....its very much fine if you complete till oct or nov...but it wil be problem for us if it extends november...so,please I humbly request you to complete by november...Great job!!!!

[@SandeepKumar-jr7ti]

sir for EMT what should be the strategy..

[@swethasri2276]

sir.. which book we need to refer for solving problems for edc for gate apart from prev year papers?

[@UnacademyFlux]

Integrated electronics by millman and halkias, solid state electronic devices by streetman, microelectronics by sedra and smith

[@prameelamadamanchi2608]

Does bonding exist for semiconductors or only for solids ?

[@UnacademyFlux]

prameela madamanchi semiconductor is also a solid

[@prameelamadamanchi2608]

thank u sir

[@saurabhjha5401]

Sir plss make vedios for control system. Sir can holes have mass ?

[@vinaykumarvinni3007]

sir plz let me know how to manage interview in psu's

[@gategoal5009]

In 2nd ques conductivity 8000 ohm inverse and current density= 80 A/CM^2

[@manishadas7434]

8000 mho

[@pujaaurangabad3056]

Awesome sir

[@tejalbhatti3464]

the second problem u told conductivity as 8000 but u wrote 800(ohm-cm) -1 2

[@manishadas7434]

sir in germanium u missed 3p6

[@mannyr9225]

I believe you missed a 3p6 level at 17:10

[@UnacademyFlux]

yes i missed 3p6..thank you

[@mannyr9225]

it's okay thank you so much. This is very helpful for a university course I am currently enrolled in.

[@tharunvelamala8959]

Sir we are following ur lectures very hardly we r preparing for gatee so plz upload in depth and more concepts

[@kasiyadav8842]

Sir in place 8000 u put only 800
