This technique utilizes the exponential dependance of the gate current in GaAs MESFETs on electron temperature in the channel. Using this new technique we measured the electron temperature as a funtion of the gate and drain bias in depletion mode ion-implanted GaAs MESFETs. These results indicate, that the random component of the electron motion is considerably reduced in constricted channels in field effect transistors.enCAD-ModellEffektive Elektronen-TemperaturGate-Strom-AnomalieHot-Elektron621667conference paper
