A III-V semiconductor heterojunction in which a capping layer (14) is formed between the two layers (10, 16) of the heterojunction to prevent any deleterious effects due to As-P exchange. When InAlAs is grown on InP, the capping layer is AlP. When GaAs is grown on GaInP, the capping layer is GaP.

摘要:
In LPE boat-slider apparatus the boat, which carries the melts, is made of lower thermal conductivity material than the slider, which carries the substrate. Illustratively, the boat comprises sapphire and the slider comprises graphite. A confined-melt geometry is also described in which another slider, used to skim off thin portions of the melt, is also made of the lower thermal conductivity material.
