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/sub 0.53/Ga/sub 0.47/As 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/sub 0.53/Ga/sub 0.47/As has been studied. Differently from what happens in GaAs-based devices, carrier multiplication increases on increasing the temperature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
