Metal induced gap states, generally formed while metal and semiconductor contact. How to distinguished the surface states and metal induced gap states?
Hi friend. Another explanation comes from the fact that the Fermi energy is the name that physicists gave to the electrochemical potential of the semiconductor. By the second law of thermodynamics, the chemical potential of all compontents of the system must be the same (i.e. constant) at equilibrium. That is a consequence of the fact that, at equilibrium, the change in Gibb's free energy = 0 and the chemical potential is a derivative of Gibb's free energy with respect to the number of particles. This all means that the Fermi level being constant at equilibrium is a consequence of the second law of thermodynamics. If you need more information, you can find basically everything about the electrochemical potential and why the chemical potential must be the same for all components at equilibrium due to the second law on Castellan's Physical Chemistry (10th ed) book. The thing about the Fermi level and electrochemical potential being the same you can find on the internet, e.g. www.researchgate.net/post/Can_we_relate_the_Electrochemical_potential_and_Fermi_level_in_Semiconductor and www.sciencedirect.com/topics/physics-and-astronomy/electrochemical-potential#:~:text=The%20energy%20at%20which%20the,electrochemical%20potential%20of%20the%20semiconductor.

Wow! Never heard of such a lucid explanation. I became a bit more wiser today
Great explanation! I was stucked in some doubts, nice having these insight!

Thank uh sir for a clear picture of the topic 🌸
Always welcome
Very well explained. Thanks
useful video thanks sir
Question1: What do you mean by cleaning to avoid pinning? what kind of cleaning is effective?
RCA1 RCA2 and pirannah cleaning.
Thanks, very useful video
See my next video on booting multiple Windows operating systems
Hi Where to find more vedio from Prof. Won park? Thanks
Goto coursera website.
One question. Why the Fermi Level should be constant throughout the system? 6.50
A gradient in the Fermi level is the driving force for carrier motion:
Fn=(nDn/kBT)(dEf/dx)
In equilibrium (zero bias), Fn=0
and therefore EF=const.
