Wet etching characteristics of cubic GaN (c GaN) thin films grown on GaAs(001) by metalorganic vapor phase epitaxy (MOVPE) are investigated.The samples are etched in HCl,H 3PO 4,KOH aqueous solutions,and molten KOH...
High quality cubic GaN (c GaN) is grown by metalorganic vapor deposition (MOCVD) at an increased growth temperature of 900℃,with the growth rate of 1 6μm/h.The full width at half maximum (FWHM) of room temperature...
