M. Passlack et al., OBSERVATION OF INVERSION-LAYERS AT GA(2)O(3)-GAAS INTERFACES FABRICATED BY IN-SITU MOLECULAR-BEAM EPITAXY, Electronics Letters, 32(3), 1996, pp. 267-269
Strong inversion has been observed at Ga2O3-GaAs interfaces fabricated
using in-situ multiple-chamber molecular beam epitaxy. The oxide mms
were deposited on clean, atomically ordered (100) GaAs surfaces at sim
ilar to 600 degrees C by electron beam evaporation using a Gd3Ga5O12 s
ingle crystal source. The formation of inversion layers in both n- and
p-type GaAs has been clearly established by quasi-static capacitance-
voltage measurements.
