    High Frequency DC Induced Oscillations in 2D

    In recent years DC induced current oscillations have been observed in many different types of 2d structures. In this paper we present results on GaAs/AlGaAs MQW structures that exhibit this behaviour at low te...

    Negative Differential Resistance, High Field Domains and Microwave Emission in GaAs Multi-Quantum Wells

    Experimental results presented in this work are concerned with high longitudinal electric field transport in n-type modulation doped GaAs/AlGaAs multiple quantum wells. Negative differential resistance with accom...

    NDR, Hot Electron Instabilities and Light Emission in LDS

    It is well known that negative differential resistance, NDR, in bulk material can occur as a result of mixed scattering1,2, non-parabolicity2,3, intervalley transfer4,5, impurity barrier capture6,7 and other esot...
