Ballistic electron emission microscopy (BEEM) was used to study the Au
/GaAs(110) interface, where the GaAs(110) surface was prepared by clea
ving. We were able to prepare Schottky barriers characterized by a hig
h homogeneity. Moreover, the interface, formed on the (110) cleavage p
lane of a GaAs(100) wafer, transmits ballistic electrons for months wi
thout any significant deterioration in contrast to the Schottky barrie
rs prepared on chemically cleaned GaAs(100). (C) 1998 Elsevier Science
