This was such an awesome lecture! I was searching for answers to these two questions: 1. A foolproof process to draw a band diagram and 2. What is Fermi level pinning. I am very much satisfied with the answers except for the second one. I would like to understand how accept or and donor type surface states affect the Fermi level pinning?
On the slide named "Contacts: Schottky Model", should it be "For Schottky contact" rather than "For Ohmic contact"? The work function of metal is larger than that of semiconductor. There is a barrier for electrons to move from semiconductor to metal.

need more to discuss the case p and metal schottky

In highly doped ITO, EF moves near or into the conduction band, so the electrons are mobile and lead to high conductivity.
30:00 interesting that in chemistry everytime you see exponential behaviour, you must think of a barrier for the reaction to go foward.
I guess it is quite randomly asking but do anyone know of a good site to stream new tv shows online ?
@Hugh Ace I would suggest Flixzone. Just search on google for it =)
35:00 silver used for contact metallization at about 10% worldwide. That number would go only up. :-)
