Injection-Current Dependence of the Acoustoelectric Signal in AlGaAs/GaAs Heterostructures

Injection-Current Dependence of the Acoustoelectric Signal in AlGaAs/GaAs Heterostructures Acoustic charge transport is studied experimentally and theoretically. To this end, an AlGaAs/GaAs heterostructure is designed and fabricated with set geometrical and electrical parameters of the layers. Its transfer characteristic is measured, i.e., the variation of output voltage with injection current. The behavior of the curve is explained within an analytical model. The conclusions are supported by numerical simulation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Microelectronics Springer Journals

Abstract

Acoustic charge transport is studied experimentally and theoretically. To this end, an AlGaAs/GaAs heterostructure is designed and fabricated with set geometrical and electrical parameters of the layers. Its transfer characteristic is measured, i.e., the variation of output voltage with injection current. The behavior of the curve is explained within an analytical model. The conclusions are supported by numerical simulation.
