Description

Surface-sensitive analysis with synchrotron radiation photoemission spectroscopy is performed to determine the bonding properties of MBE-grown CaF2 films on GaAs(001) substrates for different substrate temperatures. Ca atoms in the unoxidized state and in the 1+ oxidation state exist at the interface at high (about 580degC substrate temperature as a result of CaF2 dissociation reaction, the RHEED pattern which appears only in the high temperature condition, is related to Ca atoms in both the unoxidized state and the 1+ oxidation state. At low (about-420degC) substrate temperature, CaF2 does not dissociate. (author)
