MAGNETOCONDUCTANCE OF NONEQUILIBRIUM PLASMAS IN INSB,
Abstract
The conductance of injected and impact-ionized plasmas in p-InSb at 77 degrees K has been measured as a function of amplitude and direction of magnetic field relative to the electric field strength. Very large anisotropy in magnetoconductance occurs as the relative orientation between electric and magnetic fields is varied, and in the vicinity of the maxima large amplitude conductance oscillations develop with a frequency in the tens of MHz range. The plasma magnetoconductance for given magnitudes of applied fields abruptly drops to zero at a precisely defined orientation theta between the fields. Impact-ionized plasmas produce current-field strength characteristics with negative resistance re-ions both in the presence and absence of magnetic fields. These effects are qualitatively explained.
