We study photoinduced microwave absorption (PMA) at 36 GHz by photogenerated carriers and, in particular, the classical cyclotron resonance (CR) of both electrons and holes in undoped GaAs/AlGaAs QWs. Analyzing the CR lineshape, electron and hole cyclotron masses and their mobilities are obtained. I
The GaAs/A1GaAs semiconductor insulator semiconductor (SIS) structure used for high-performance field effect transistors has also been used in the study of parallel coupled transport between electrons in the FET n Γ· gate(3D) and channel (2D). At temperatures above 50K the predominant coupling involv
