Current Instability in n-and p-Type InSb under Crossed Electric and Magnetic Fields

The current density and the Hall coefficient of n-and p-type InSb were measured as a function of electric field, E, up to 1000 volt/cm in a transverse magnetic field, H, from 1000 to 6000 gauss at 77°K. In n-InSb, for H>2000 gauss, incoherent current oscillations with frequency of 20∼50 Mc/sec set i... View More
