Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to get suggestions about the physical meaning of the (1) flat-band voltage and the (2) Fermi-level.

Before being marked as newbie, I'd like to point out that I know how to calculate them and know that the

(1) flat band voltage is the one which you apply, the energy band will be straight

(2) the Fermi-level is the energy level where the probability of occupancy for electrons is 1/2.

So I know the calculations and these definitions but I am somehow struggling with linking them to straight understandable physical phenomenons...can somebody please explain.

Thanks,
