Since the larger energy gap of (A1(x)Ga(1-x))(y)In(1-y)P has the        potential for larger conduction band discontinuity and can give                 insulator behavior, research is proposed to demonstrate MODFET's and            inversion mode MISFET's utilizing layers of (A1(x)Ga(1-x))(y)In1-yP on          GaAs.  This work will begin by modifying an existing OMCVD reactor to           allow growth of the GaAs-(A1(x)Ga(1-x))(y)In(1-y)P heterojunction.              Growth studies will include impurity incorporation and characterization         of the electrical properties at various growth temperatures and III-V           ratios in the input gas stream.  Measurements will be made to                   characterize the (A1(x)Ga(1-x))(y)In(1-y)P layers and the GaAs-                 (A1(x)Ga(1-x))(y)In(1-y)P heterojunction interface.  High resistivity           (A1(x)Ga(1-x))(y)In(1-y)P layers on GaAs will be evaluated and the              fabrication technology will be investigated to permit the fabrication           and evaluation of MODFET and MISFET devices.  Possible configurations           for complementary MIS circuits and three-dimensional structures based on        GaAs-(A1(x)Ga(1-x))(y)In(1-y)P heterojunctions will be investigated.
