Re: Holes, Positrons

Another key consideration is that only one positron is generally  around at
any given time. With no Pauli exclusion to keep it at a high energy it will
quickly thermalized to an energy of something like 0.025 eV prior to
annihilating. This is unlike the electrons in a metal where the electrons
taking part in conduction are up at the Fermi energy of several eV.
