Abstract
Strain-compensated InAlAs/lnGaAs HEMT structures, grown on InP substrate, h ave been investigated in terms of structural and electrical properties. Fro m detailed x-ray diffraction (XRD) investigations the compensation index an d the evolution of the strain state were measured. We show that a partial a nd controlled strain compensation significantly improves the structural qua lity and the thermal stability of HEMT structures as well as their electric al properties.
