Nitridation and CVD Reactions with Hydrazine

The lowtemperature nitridation of gallium arsenide, silicon and transition metals was investigated using hydrazine. Gallium nitride films were grown on gallium arsenide (GaAs) by direct reaction of the semiconductor surface layers with hydrazine at 200 —4000C. Auger electron spectroscopy and Xray photoelectron spectroscopy (XPS)

Gallium nitrate Wikipedia

Gallium nitrate (brand name Ganite) is the gallium salt of nitric acid with the chemical formula Ga(NO 3) is a drug used to treat symptomatic hypercalcemia secondary to cancer. It works by preventing the breakdown of bone through the inhibition of osteoclast activity, thus lowering the amount of free calcium in the blood. Gallium nitrate is also used to synthesize other gallium compounds.

In this paper, gallium nitride (GaN) growth chemistry is characterized by two competing reaction pathways. An overview of GaN gasphase and surfacephase chemistry is used to generate a comprehensive model for epitaxial GaN growth from the commonly used precursors, trimethylgallium ((CH 3) 3 Ga) and ammonia (NH 3).The role of reactor geometry in controlling the selectivity among …
