Abstract
The density of interface states at the epitaxial CaF2-Si(111) interfac e grown under UHV conditions at 700 degrees C is found to be much lowe r than assumed previously, as revealed from photoelectron spectroscopy . An upper limit is estimated to be 3 x 10(12) cm(-2) eV(-1) near midg ap, which comes close to values obtained for SiO2-Si interfaces.
