Deposition of amorphous silicon alloys

Hydrogenated amorphous silicon alloys of carbon and germanium can be deposited by glow-discharge decomposition of gaseous hydrides or fluorides. Non-plasma methods such as photochemical vapour deposition are also used and offer guidelines for understanding and improving the standard glow-discharge method. These amorphous alloys usually have poorer structural and electronic properties than pure ...

Application of Pulse Plating - Amorphous Alloys

Amorphous alloys can be electrodeposited by direct or pulsed current. According to electrocrystallization theory, a high crystallization overpotential produces microcrystalline structure in the deposits. Thus if the amorphous phase consists of microcrystals, pulsed current is preferable for preparing amorphous alloys. However, another newly proposed theory holds that the amorphous phase structu...
