Photoemission Studies of the M/Si(111)-3x1 Reconstructions for M=Li, Na, K, and Ag
2003 (English)Licentiate thesis, monograph (Other academic)
The work reported here relates to a class of reconstructions on the Si(111) surface with 3?1 or 6?1 periodicity that are believed to be similar for Ag, Mg and the alkali metals (Li, K, and Na). The electronic structure of this reconstruction was studied by means of angle-resolved photoelectron spectroscopy of the valence bands of the Ag/Si(111)-3?1/6?1 reconstruction. Theoretical valence band maps calculated using Density Functional Theory (DFT) were found to agree well with the experimentally obtained valence band maps for the Ag/Si(111)-3?1/6?1 reconstruction. The geometric structure and bonding was investigated by core-level spectroscopy of the M/Si(111)-3?1 surfaces for M=Li, K, and Na, as well as the Ag/Si(111)-3?1/6?1 and Ag/Si(111)-c(12?2) reconstructions.
