摘要

The metallorganic precursor of phenylhydrazine has been used as a nitrogen source to grow GaN and AlN on (100) Si, (100) GaAs and (0001) Sapphire using low pressure MOVPE. The feasibility of GaN and A1N growth is demonstrated and the growth characteristics are analyzed. The growth of GaN took place in the range of 500℃ to 600℃ and growth rates were typically 1μm/hr. TEM studies show the presence of GaN crystallites of about 30nm in size in the layers grown. A shift of 1.3 eV for the Ga_3d binding energy and presence of both atomic nitrogen and partially dissociated fragments of NH and NH_2 was revealed by XPS.
