Determination of the transport parameters in two-dimensional semiconductor systems and thin films by contactless microwave methods
Proceedings. 3rd Annual Siberian Russian Workshop on Electron Devices and Materials - Tập 1 - Trang 75-76 - 2002
Tóm tắt
The results of theoretical and experimental study of Shubnikov-de Haas effect and cyclotron resonance by microwave methods (/spl omega//2/spl pi/=37.8GHz) in AlGaAs/GaAs heterostructures are presented. The theoretical expressions for the determination of the carrier concentration and mobility are obtained. With these data, the transport parameters in two-dimensional systems and thin films can be determined with an accuracy /spl sim/0.5%.
