Abstract

The In growth on cleaved GaAs(110) surfaces at room temperature (RT) and 80 K low temperature (LT) as well as the initial stage Schottky barrier formation at this interface has been studied using photoelectron spectroscopy. In grows as 3-D islands at RT, but in Stanski-Krastanov mode at LT. The size of the clusters has been estimated through an intensity study. The In core level spectra continuously shifts to high binding energy direction in the transformation from isolated atoms to bulk metal. The Fermi level pinning pattern shows a strong temperature dependence, which challenges current models of Schottky barrier formation at metal/semiconductor interfaces.
