Abstract
The material characteristics of MBE grown AlInAs layers relevant to AlInAs/InGaAs HEMTs, such as surface morphology, specific resistivity, doping and Schottky contact behaviour, have been investigated for dependence of the growth temperature. Respective optimum results were obtained at different temperatures which were adopted for the growth of HEMT structures. Preliminary results on 1 mu m gate length devices are presented.
