The Effect of Magnetic Field on the Low-Temperature Breakdown in Highly Compensated Germanium

Abstract

The effects of magnetic field on the negative resistance characteristics of highly compensated P-type germanium at 4.2°K are presented. It is shown that the sustaining field strength, E_s, varies linearly with the magnetic field, H.
When the magnetic field strength is sufficiently high an oscillation phenomenon is observed in the sutaining region.
The value of E_c, the electric field strength at the critical point, shows an angular dependence on the transversal magnetic field. This angular dependence is different for different transversal magnetic field strength.
