Angle-Resolved Photoemission Study of AuGa2 and AuIn2 Intermetallic Compounds.
Abstract
The (001) surfaces of AuGa2 and AuIn2 intermetallic compounds were studied using synchrotron radiation excited angle-resolved photoemission. Spectra collected for photoelectron emission normal to the sample surfaces were used to map the E versus k dispersion relation of both compounds along the delta symmetry line of the bulk Brillouin Zone. The results show that the Au 5d bands of each compound are relatively flat, but the splittings of the bands at gamma are nearly the same as for elemental Au. A surface state is also observed on each surface in a band-gap region about 6 eV below the Fermi levels of the 2 compounds. Originator furnished keywords include: Synchrotron radiation - angle-resolved photoemission - valence band structure - d-bands - surface state.
