Abstract

Growth of In-related nitride semiconductors was investigated by means of metalorganic vapor phase epitaxy (MQVPE) and halide vapor phase epitaxy (HVPE). Semi-polar {101^^-3} InN crystal was grown on GaAs (110) substrates by MOVPE. Mechanisms of twin formation and influences of lattice polarity on the crystalline quality of InN were clarified. On the other hand, growth of thick In_xGa_<1-x>N alloy crystal by HVPE was studied by thermodynamic analysis. It is suggested that growth of In_xGa_<1-x>N alloy with good composition controllability is attained even at relatively high growth temperature by the control of V/III ratio and hydrogen partial pressure in the system.
