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.

One clear difference between the object commonly known as a "hole" and a
positron is that a hole can exist in the presence of matter without
annihilating with the nearest electron (of which there are an abundant
number to provide for almost immediate conversion to photons). Since it
appears that a hole can exist in normal matter, it is clearly different
from a positron.

How does a hole differ from a positron? Would they act electrically the
same in a s/c?

A file that big?
It might be very useful.
But now it is gone.
