GAAS SINGLE CRYSTAL MANUFACTURING METHOD

摘要

controlling an As pressure in an ampule by controlling a stoichiometry of the presynthesized polycrystal As, adding doping elements of Si or Zn to the ampule in time of polycrystal synthesis; controlling the As pressure to synthesize the polycrystal on the condition that the doped polycrystal synthesis is different from the undoped polycrystal synthesis in melt stoichiometry.
