Electronic excitations on the alkali - metal ( Na , Cs ) - adsorbed Si ( 111 ) 7 × 7 surfaces

Electronic excitation spectra of the alkali-metal (AM) (Na,Cs)-adsorbed Si(111)7×7 surfaces have been investigated by using high-resolution electron energy loss spectroscopy. We find that AM induces metal–semiconductor transitions at the early stage of adsorption by completely filling half-filled Si adatom dangling-bond states. A loss peak of energy less than 0.31 eV appears as a precursor of t...

Theory of alkali-metal-induced reconstruction of fcc (110) surfaces.

Molecular switches from benzene derivatives adsorbed on metal surfaces

Transient precursor states are often experimentally observed for molecules adsorbing on surfaces. However, such precursor states are typically rather short-lived, quickly yielding to more stable adsorption configurations. Here we employ first-principles calculations to systematically explore the interaction mechanism for benzene derivatives on metal surfaces, enabling us to selectively tune the...

Experimental and computational studies of alkali-metal coinage-metal clusters.

Coinage and alkali metal mixed clusters, M4Na- (M = Cu, Au) have been investigated experimentally using photoelectron spectroscopy and computationally at correlated ab initio levels. The related Cu4Li-, Ag4Li-, Ag4Na-, and Au4Li- clusters as well as the neutral Cu4Li2 and Cu4Na2 clusters have also been studied computationally. The calculations show that the two lowest isomers of the negatively ...
