  • Abstract
    We report, for the first time to our knowledge, the characteristics of In0.5Ga0.5P/In0.22Ga 0.78As/GaAs p-HEMTs with a 50 Å gate oxide layer implemented by the liquid phase oxidation of GaAs. This enhances the on-state and off-state breakdown voltages compared to those of p-HEMT without a gate oxide layer, permitting a trade-off between channel current driving capability and both breakdown voltages
