On- and off- state breakdown effects in composite channel and conventional InP-based HEMTs are studied by means of electrical measurements, and electroluminescence spectroscopy. We demonstrate that channel quantization increases off-state and on-state breakdown voltage. The temperature coefficient of the electron impact ionization rate in In 0.53Ga 0.47As has been studied. Differently from what happens in GaAs-based devices, carrier multiplication increases on increasing the temperature.

Abstract
On- and off- state breakdown effects in composite channel and conventional InP-based HEMTs are studied by means of electrical measurements, and electroluminescence spectroscopy. We demonstrate that channel quantization increases off-state and on-state breakdown voltage. The temperature coefficient of the electron impact ionization rate in In 0.53Ga 0.47As has been studied. Differently from what happens in GaAs-based devices, carrier multiplication increases on increasing the temperature.File in questo prodotto:
