Tunable electron heating induced giant magnetoresistance in the high mobility GaAs/AlGaAs 2D electron system
Electron-heating induced by a tunable, supplementary dc-current (I(dc)) helps to vary the observed magnetoresistance in the high mobility GaAs/AlGaAs 2D electron system. The magnetoresistance at B = 0.3 T is shown to progressively change from positive to negative with increasing I(dc), yielding nega...
