Abstract

We calculate the current density in a semiconductor superlattice with\nparabolic miniband under crossed non-quantizing electric and magnetic fields.\nThe Corbino disk geometry is considered. The current-voltage curve contains\noscillations with period proportional to the magnetic field. The possibility is\nshown of the negative absolute conductivity. The Ampere-Gauss characteristics\nalso contain overshoots under high enough electric fields. In all cases, the\npeaks smear with temperature rising.\n
