Surface resonance on the (6 root 3 x 6 root 3)-R30 degrees-reconstructed 5 ML Au on (root 3 x root 3)-R30 degrees-4H-SiC(0001)
(2007) In Surface Science 601(12). p.2508-2511- Abstract
- In this paper we present evidence for a surface resonance on the (6v root 3 x 6 root 3)-R30 degrees-reconstruction obtained on 5 monolayers (ML) of An deposited on the (root 3 x root 3)-R30 degrees-4H-SiC(0001) and subsequently annealed. We use synchrotron radiation-based angle resolved photoelectron spectroscopy to show that this resonance has no k(parallel to)-dispersion, but a parabolic-like kil-dispersion of 0.4 eV around Gamma. Its electronic localization in the (6 root 3- x 6 root 3-)-R30 degrees surface reconstruction is documented by comparison with the (2 root 3- x 2 root 3-)-R30 degrees structure, obtained at a slightly lower annealing temperature after 5 ML Au deposition on the (root 3- x root 3)-R30 degrees-4H-SiC(0001)...
