S. Torii et al., FORMATION OF INAS WIRES AND DOTS ON VICINAL GAAS(110) SURFACES WITH GIANT STEPS BY MOLECULAR-BEAM EPITAXY, JPN J A P 2, 36(12B), 1997, pp. 1645-1647
InAs are grown on vicinal GaAs (110) surfaces with giant steps using m
olecular beam epitaxy. Atomic force microscopy, X-ray photoelectron sp
ectroscopy and transmission electron microscopy show that uniform and
well-aligned InAs wires and dots are formed on the facets at giant ste
p edges due to the accumulation of InAs. This accumulation is only obs
erved in a relatively high growth temperature range (580-600 degrees C
) and not at low temperatures.
