Sw. Wilson et al., (766) ORIENTED V-GROOVE SURFACES ON BR-2-CH3OH ETCHED (100)GAAS WAFERS, Journal of materials science. Materials in electronics, 8(2), 1997, pp. 109-113
Etched V-grooves on (100) gallium arsenide crystal surfaces produced u
sing various compositions of bromine-in-methanol etchant are bounded b
y sidewall surfaces, presumably of Ga atoms, aligned along the origina
l {766} position of the bulk crystal as determined by optical and elec
tron microscope observations. The measurements are tentatively explain
ed by rotational surface reconstruction of Ga-deficient, rehybridized
{111} planes.
