Abstract :
Application of the hydride growth process at overall pressures below 5Ã103 Pa yields very high rates of deposition for binary (GaAs, InP) and ternary (GaInAs, GaAsP) III-V semiconductor films. It is proposed that at these conditions the hydrides AsH3 and PH3 reach the substrate surface undecomposed and react directly with the group III chloride (GaCl, InCl). The rates can be convenently adjusted over a wide range by varying the reactant pressures. Films of excellent morphology with low background doping, high electron mobilities and well resolved PL spectra were obtained.
