Sir on heating n-type semiconductor you said that the fermi level will shift downwards because more and more electrons from valance band will jump to conduction band leaving holes ... but sir isn't the no. Of electrons jumping= no. Of holes created so fermi level should not be disturbed as in case of intrinsic semiconductor? Please reply

In case of intrinsic semiconductor fermi level will remain same as number of holes in valence band will always be equal to number of electrons in conduction band at all temperatures. In p-type and n-type semiconductors, it will not be the case. Please watch the video carefully.. It is explained in the video.

Sir i having a doubt as we know if we increase temperature in intrinsic semiconductor the enery gap is decreased due to high concentration of electron but why fermi level is same

I can not understand the idea of Fermi levels shifting in doped semiconductors towards those of in intrinsic one with the increase of temperature. It seems to me they should remain unchanged. The thing, I understand that in extrinsic semiconductor the formed "donor" and "acceptor" band is not similar with Fermi level ?

Sir if we increase the temperature, than same number of electron hole pair will be there.. So if we increase the temperature then fermi level will remain in its old position .. Please explain

Is Doping Level In ptype and N type is Similar or Different. Explain In brief
@EngineeringPhysicsbySanjiv
@EngineeringPhysicsbySanjiv 3 жыл бұрын
Doping levels in p-type and n-type semiconductor may be same or different. The penetration of the depletion layer in p-type and n-type semiconductor depends on the doping level.
