Summary:
Fermi-Dirac distribution
I`m sorry if this seems too obvious, just trying to clarify something. When Fermi-Dirac distribution is equal to zero , can we assume it is the state of

the highest energy? (Because the propability of occupation is zero)

##f(\epsilon)## goes to zero as ##\epsilon \rightarrow \infty## for a finite temperature (##T>0##).

At absolute zero, ##T=0##, then ##f(\epsilon > \epsilon_\mathrm{F}) = 0##, where ##\epsilon_\mathrm{F}## is the Fermi energy.
