  • Abstract
    We have obtained an optimised HEMT structure with a high 2DEG sheet concentration of 1×1012 cm¿2 while maintaining a high 77 K electron Hall mobility of 120,000 cm2/Vs. The structure utilises a 45% Al mole fraction AlGaAs barrier and a 20% Al mole fraction doped region. It has little or no light sensitivity at 77 K.
