Negative Magnetoresistance - an overview ScienceDirect Topics
WebMagnetoresistance (MR) effects have been investigated in perpendicular and parallel magnetic fields at 300, 80 K and liquid He temperatures for undoped InSb thin films 0.1- 2.3 μm thick grown on GaAs(1 0 0) substrates by MBE. WebA negative magnetoresistance proportional to B2 is found in the two-dimensional electron gas of GaAs- AlxGa1−xAs heterostructures. It is explained by the conductivity correction due to the electron interaction effect in disordered two-dimensional systems.
