Abstract
The hot carrier d.c. conductivity of a degenerate many valley semiconductor has been investigated, using the effective carrier temperature approximation. Comparison of these results with earlier work on nondegenerate semiconductors shows that the effect of degeneracy is to reduce the anisotropy and carrier heating by d.c. field (thus making Ohm's law applicable up to higher fields). Further it is seen that degeneracy leads to increase of conductivity with increasing electric field; this is in contrast to the results for the nondegenerate case.
