Abstract

A large number of spectral structures are observed by far infrared magneto-photo-conductivity in n-GaAs at 4.2K biased above impurity breakdown in a regime where current flow is filamentary. Phase changes are found in the center of the 1s−2p+1 line and new structures are observed which shift to higher magnetic fields with increasing bias voltage. The large strength and the intensity dependence of ...
