Wn. Rodrigues et al., HETEROEPITAXIAL GROWTH OF INAS ON GSAS(100) MEDIATED BY TE AT THE INTERFACE, Solid state communications, 95(12), 1995, pp. 873-877
The heteroepitaxy of InAs on a Te covered GaAs surface is investigated
by photoelectron spectroscopy. Core-level spectra probed with synchro
tron radiation show that Te remains at the interface between InAs and
GaAs in a concentration much higher than the solubility limit of this
element in III-V compounds, suggesting that a new compound is being fo
rmed. We propose that this interlayer is responsible for the observed
changing in the growth mode of the InAs overlayer from islands to laye
r by layer.
