When one chooses to regard the current as being carried by positive holes rather
than negative electrons , the electrons are best regarded as merely the absence
of holes ; i . e . , levels occupied by electrons are to be considered unoccupied ...

A hole current flows from the n - to the p - side of the junction , known as the hole
generation current . As the name indicates , this current arises from holes that are
generated just on the n - side of the depletion layer by the thermal excitation of ...
