Electronic structure of atomic chains on vicinal Si „ 111 ... - Au
Unusual electronic states are found for gold-induced chain and ladder structures on vicinal Si~111! surfaces, such as Si(111)532-Au and Si~557!-Au. As two-dimensional reference the Si(111)A33A3-Au surface is investigated. The highly stepped Si~557!-Au surface is metallic, despite an even electron count. That is explained by two half-filled, nearly degenerate bands. On the Si(111)532-Au surface ...
متن کاملStep-Induced Optical Anisotropy of Vicinal Si(001)
It is demonstrated, using reflectance difference spectroscopy, scanning tunneling microscopy, and low-energy electron diffraction, combined with deliberate straining of the surface, that the presence of atomic steps dramatically changes the optical anisotropy of the Si(001) surface. The step-induced reflectance difference signal originates predominately from rebonded steps and is comparable in ...
متن کاملFermi surfaces of surface states on Si „ 111 ... - Ag , Au
Metallic surface states on semiconducting substrates provide an opportunity to study low-dimensional electrons decoupled from the bulk. Angle resolved photoemission is used to determine the Fermi surface, group velocity, and effective mass for surface states on Si(111))3)-Ag, Si(111))3)-Au, and Si(111)A21 3A21-(Ag1Au). For Si(111))3)-Ag the Fermi surface consists of small electron pockets popul...
متن کاملRectangular nanostructuring of Au(111) surfaces by self-assembly of size-selected thiacrown ether macrocycles.
Surface modification by self-assembled monolayers (SAMs) has continuously attracted considerable attention because of several potential applications in domains such as nanopatterning, biosensors and chemical sensors, and microelectronics.1,2 Organo-sulfur derivatives such as n-alkanethiols R-SH and dialkyl disulfides R-SS-R′ are the most extensively studied SAMs adsorbed on various metal surfac...
متن کاملPhonons of Metallic Vicinal Surfaces
We present an analysis of the vibrational dynamics of metal vicinal surfaces using the embedded atom method to describe the interaction potential and both a real space Green’s function method and a slab method to calculate the phonons. We report two main general characteristics : a global shift of the surface vibrational density of states resulting from a softening of the force field. The latte...
