Q1:

If E is energy level of electron and EF is fermi level, and T = 0 and E > EF, then

A the probability of finding an occupied quantum state of energy higher than EF is zero

B all quantum states with energies greater than EF are occupied

C some quantum states with energies greater than EF are occupied

D majority of quantum states with energies greater than EF are occupied

ANS:A - the probability of finding an occupied quantum state of energy higher than EF is zero

Probability of finding should be max in energy state greater than fermi energy level.
