This industry/university cooperative research program is concerned with         an understanding and improvement of the various structural and                  materials effects determining the performance of the modulation-doped           FET's including their thermal stability and millimeter-wave power               gains.  For thermal stability, the conventional n-AlGaAs layer on GaAs          buffer layer will be replaced by a short period n-GaAs/AlAs                     superlattice.  This configuration will be used to achieve submicron             gate-length MODFET's with optimized gate layer thickness to improve the         device power gain stability margin at mm-wave frequencies.  Additional          design refinements will be incorporated to reduce the device output             conductance and contact series resistances.  Detailed electrical                characterization and modeling of the improved MODFET's, first to                support the structural design optimization process and then to extract          the basic electrical and physical parameters that are indicative of the         HF potential of the optimized devices will be performed.
