Electron-hole gas density in different materials

  1. May 17, 2015 #1
    If we connect a two metals with different Fermi levels electrons will start to flow from metal with higher Fermi level to a lower one. Untill metal with lower Fermi level will get negatively charged and the process will stop.
    But what if we connect a two materials with different Fermi levels, but equal conductivity of both electrons and
    holes? Will holes start to get transferred between these materials too, and if yes, how exactly?

    How do you define a hole in a metal?

    I do not know, but does positive Hall coefficient in metals exists?

    It does, for example in aluminium. But this does not mean that the charge carriers are holes.

    What then?
