Electronic Devices Lecture-7: Energy-band Structure of Insulator, Semiconductor and Metal

[@SHREEdharSimple]

Happy Teachers Day Sir..!!

[@chiragpandya2944]

These lectures are super, easy to understand. Is there videos of any other subjects? What is your name, sir?

[@krishna16181]

sir u r awsome.... keep going sir....

[@srinivaschowdaryappasani2248]

sir how ....energy band gap of 1.21ev at 0 kelvin act as .....insulator which has 5ev band gap.....please clarify sir

[@shilparamisetty7048]

In 6: 33 if the electron is bonded how can it move into conduction band.. ?!!!

[@rohitdatwani8467]

Sir I have a doubt that u said in last 10 sec of the video that energy band gap for metals is approx zero at 300k this means conductivity of metals increase on increasing temp but this is not true bcoz on increasing Temp resistance of metals increase correct me if I am wrong? Plz

[@prithvirajkothandan4528]

sir please upload control system lectures instead of edc

[@priyatam17]

Ionic bonding is there in insulator..or covalent bonding?

[@udayputta711]

in insulator ionic bond Semiconductor is Covalent bond

[@sujathagangi302]

sir, 1 -> "Conduction band has electrons and valence band has holes" ; 2 -> " Minimum energy (Energy gap, Eg) if we give to electron in the hole then electron will move to conduction band and will act as carrier for current" Till what extent i am correct in these 2 statements. Pls help me in correcting myself. Thank you sir!

Sujatha gangi condutction band will have free electrons , valence band will have bounded electrons..if we apply sufficient energy bounded electrons will move from valence band to conduction band and becomes free, and they will participate in the current conduction

Thank you

[@skyadav137]

thank you sir

thnk u so much sir ..😎
