Abstract
From experiments on internal photoemission of electrons at the (100)InSb/Al2O3 interface, the top of the InSb valence band is found to be 3.05 +/- 0.10 eV below the oxide conduction band and corresponds to a conduction band offset of 2.9 +/- 0.1 eV. These results indicate that the top of valence band in InSb lies energetically at the same level as in GaSb and above the valence bands in InxGa1-xAs (0
