The quantum Hall effect in modulation doped In0.53Ga 0.47As-InP heterojunctions

Abstract
We report the first observation of the quantum Hall effect in modulation doped In0.53Ga0.47As-InP heterojunctions at 4.2 and 1.5 K. The results are then compared to data obtained in a GaAs-Al xGa1-xAs heterojunction having similar electronic characteristics
