Abstract

Abstract : The modification of the Au(111) Shockley surface state (SS) by an n -alkane molecule ( n -tetratetracontane) monolayer was observed by angle-resolved ultraviolet photoemission spectroscopy. Abstract : The modification of the Au(111) Shockley surface state (SS) by an n -alkane molecule ( n -tetratetracontane) monolayer was observed by angle-resolved ultraviolet photoemission spectroscopy. Although there is little chance of chemical interaction in this ideal physisorption system, the volume of the Fermi surface of the SS was significantly reduced accompanied by the formation of large interface electric dipoles. Moreover, Rashba splitting of the SS by spin–orbit interactions was slightly increased upon n -tetratetracontane adsorption, which arose from the decrease in the symmetry of the wave function around the Au nuclei at the surface. The detailed information about the simple physisorption system presented in this paper provides basic knowledge for understanding the electronic structure at the interface between other organic molecules and metal substrates.
