Abstract : The efficient preparation of a new polymeric gallium imide, (Ga(NH)3/2), from the reaction between Ga(NMe2)32 and NH3 at ambient temperatures is described. The gallium imide precursor is shown by TEM and XRD studies to yield, upon pyroysis, a rare cubic/hexagonal variety of gallium nitride, GaN. Some control over the average particle size of GaN in the nanosized region is achieved by application of various pyrolysis schemes.
