Electronic Study of Pt-Ga Intermetallic Compounds Using X-Ray Photoemission Spectroscopy
Abstract
Single-phase films of Pt-Ga intermetallic compounds with different stoichiometric compositions were grown using molecular beam epitaxy (MBE) and investigated with X-ray photoemission spectroscopy (XPS). The qualitative aspects of the peak shifts and shapes are consistent with those of other compounds that have been previously investigated. Semi-quantitative analyses show that the valence bands are dominated by Pt-Ga hybridization, rather than by Pt d-d interactions, and that the final state effects dominate initial state charge transfer in determining the binding energies (BE) of the Pt core level peaks.
