Electronic Devices: Hole concentration - derivation

[@preethipara8028]

Watched 1st seven videos of this playlist...so far....so good..thank you sir🙏..going to watch next series of videos..

[@techgurukula]

Thank you Preethi!

You saved my life ~ thank you so much !

Why integrating from -infinity to Ev As energy is not negative. So why can't integrate from 0 to Ev

[@tolgaaks167]

What happens to minus sign in ktdx?

[@devbratsrivastava9987]

Reversed the integration limits from infinity -> 0 to 0-> infinity

[@saikumarPatnalaNASA]

Someone pls help me... Is it that.. only a single electron can be there in a particular energy level?? Bcoz in derivation of calculating concentration we mean the same I think...

[@lakkupraveen2896]

no two electrons should occupy the same energy level according to Pauli's exclusion principle.

[@chintuadhana7075]

@@lakkupraveen2896 bro get ur definitons right. Pauli's principle states that no two fermions can occupy same "quantum state'"

[@chintuadhana7075]

There can be two electrons in the same energy level with opposite spin.

Thanks lot

what is 3KT?

[@deeparnabrakshit9687]

boltzmann constant

[@devimeenatchibalamurugan3272]

+Deeparnab Rakshit thank u for ur response

[@Ahmet-sq6jn]

Boltzmann Constant is k. {(E-Ef) > 3kT} assumption is Boltzmann Approximation.

Where are you now brother?

[@michaeljburt]

Out of sheer curiosity here... are the commenters here mostly electrical engineering or physics?

[@michaeljburt]

Also great job on the video. Forgot to mention. I occasionally review material like this because it's so foundational to different semiconductor configurations that are out there

in spanish plis :D
