RESONANT MAGNETOTUNNELING IN DOUBLE-BARRIER STRUCTURES

In this paper we consider the influence of ''mass barrier'' and elasti c scattering processes on the shape of j(V) and j(B) characteristics. Two scattering mechanisms, i.e. Coulombic on ionized impurities and on potential fluctuations in double-barrier structures are considered. T he ''mass barrier'' shifts the whole j(V) characteristic slightly towa rds lower voltage and makes the resonant energy ER dependent on magnet ic field. On the other hand, both considered scattering mechanisms cha nge the shape of j(V) and j(B) characteristics by shifting the oscilla tion maxima towards lower applied voltage.
