7:42 Band gap is supposed to be a distance then how we can measure it in electron volt, ev is energy unit?
@tarunkumarkottapu30225 ай бұрын
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

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

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.

Sir,is the bang gap empty? If so...how can we differentiate between band gap nd empty band?
@Upgradezz4 жыл бұрын
Empty band is a band. Band gap is the difference in every between two adjacent bands
@ArifKhan-nq4ru4 жыл бұрын
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.

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?

It is called quantum tunneling search it

Why did the 2m come in the denominator 16:46
@ishandhawan90114 жыл бұрын
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
