摘要
A combination of ion implantation and plasma enhanced chemical vapour deposition (PECVD) has been used to synthesise amorphous gallium nitride (a-GaN). This was achieved by implanting PECVD amorphous silicon nitride (a-SiN(x):H) films with 75 keV Ga(+) ions at room temperature. A study of an entire range of a-SiN(x):H films with different compositions has enabled the choice of an optimum composition of the substrate for Ga implants. An FTIR study reveals the presence of GaN bond vibrations in the N rich samples. This complements the X-ray photoelectron spectroscopy results that confirm the presence of GaN bonds in samples.
