Direct Measurement of Doping Density and Barrier Lowering Effect with Bias in Quantum Wells
Abstract
An experimental method for determining the doping density in thin-sheet semiconductor material such as quantum wells (QWs) is demonstrated in GaAs/AIGaAs multiquantum-well infrared photodetectors. The results agree very well with the conventional Hall measurement method. Barrier lowering effect with bias in QWs is determined experimentally.
