Introduction to energy bands

[@educationalstuff186]

God gifted to watch this type of lectures for an ordinary student

[@DeepakKumar-yo7xd]

Every electrical engineering student must watch this.

[@ravita2950]

Electronics also

[@ayushsingh4147]

Plzz share more playlist for 1st year BTech

[@bharadwaj767]

Wow!! I was watching the whole lecture with my jaws open 😂... There's so much to learn 😍

[@anurag-yadav]

Very useful lectures, explained concept very easily.

[@Umeshyadav-ju7gx]

Wow yur teaching style is too good sir love you sir

[@ramkrishnayadav9335]

thank you sir for your pricious lecture. 🙏🙏🙏

[@shilpas979]

Excellent teaching sir.. thank you

[@omkarmaurya3200]

Excellent explanation sir ,thankyou

[@rohanshinde9714]

Awesome sir loved the way you told about band gap formation

[@user-fe6ir1qx5x]

u r great sir

[@pawanchandrajoshi2864]

u r really a great teacher thnx for ur efforts on videos it help me lot

[@kodammathematics1657]

Very useful lectures Sir will you plz refer me any book to study all des concepts which you taught in the lectures

[@arvindnanjundaswamy2442]

Beautiful rendition

[@ramkrishnayadav9335]

thank you sir i m learning with you 🙏🙏🙏❤️❤️❤️

[@shivangsingh5834]

so impressive sir

[@Chad-_-Oogway]

19:08 electron will move in opposite direction as given on board

[@abhi2216]

7:42 Band gap is supposed to be a distance then how we can measure it in electron volt, ev is energy unit?

[@tarunkumarkottapu3022]

Band gap means that difference in energy levels There may be difference in distances in energy levels in accordance with bohr distance but we are interested in energy soo We considered energy band gap

[@salem201188]

Not explaining by details. I think these courses require solid state understanding first.

[@MMTRINATHSOLASA]

Awesome sir

[@ashutoshjha7224]

very helpful sir .Thank you

[@masterabhaygoyal2769]

Excellent explanation

[@freeandreliablejeeprep820]

thank you sir very much

[@kousikmishra3894]

Sir , as we know that defining position of e is almost impossible, then how could we controll the number of e incase of semiconductor which you have mentioned.

[@Neeraj-is1jt]

Relevant thing for me only start from 5:00 to 6:30

[@veeru730]

Thank you Sir 💯💯💯💯💯💯🙏🙏🙏🙏🙏🙏🙏

[@naiyarafzal6740]

thanku sir😊

[@umeshsharma-dm8vl]

Sir, I want to give you something as gurudakshina . How can I do so ???

[@navdeepbedibedi360]

Thanku sir 🤗🙏

[@Neelima123]

Sir,is the bang gap empty? If so...how can we differentiate between band gap nd empty band?

[@Upgradezz]

Empty band is a band. Band gap is the difference in every between two adjacent bands

[@ArifKhan-nq4ru]

Band gap is the forbidden region where electrons are not allowed to exist as per allowed quantum energy states. Conduction Band has allowed quantum energy states where electron can exist, but are empty.

[@tarunkumarkottapu3022]

Sir why the energy shells splits into 4N and 4N equally

[@ZERO-mt1lv]

Sir, Is it possible to alter the energy gap of a semiconductor?

[@pujitadas377]

sir, in which video did you tell the concept ,that even if the electron has less thermal energy it has a probability to excite from valance band to conduction band?

[@Neeraj-is1jt]

It is called quantum tunneling search it

[@gauravbisen3440]

Can you please arrange order of the videos

[@ParminderKaur-zm4kw]

Can any one please tell me how the energy band gap of any material is calculated???

[@deepakgupta3230]

From where we get pdf of note

[@piezero_567]

From nptel site Search writing the course name.....

[@ishantrivedi5588]

What's periodic potential

[@mrmkkryt6485]

Why did the 2m come in the denominator 16:46

[@ishandhawan9011]

hk is the momentum. Which is basically mv. Since we write (hk)^2, that represents m^2.v^2. KE is m.v^2/2. So it's divided by 1/2m

[@gauravbisen3440]

they are shuffled up.

[@sumaiya3763]

Would I get the slide pdf.? 🥹🥹🥹
