摘要: The effect of an ammonium sulfide treatment on the GaAs (100) surface has been investigated by x‐ray photoelectron spectroscopy. produces a slight Ga enrichment and leaves roughly 0.6 monolayer which inhibits initial oxidation surface. is not lost as becomes oxidized but appears to remain near GaAs/oxide interface. Furthermore, in layer, As oxide preferentially drawn relative oxide.
