Resonant electron capture by C60 ions at a metal surface with projected band gap
نویسندگان
چکیده
C+60 and C 2+ 60 ions are scattered under grazing incidence from an atomically clean and flat Be(0001) surface at keV energies. Distances for electron transfer are deduced from shifts of angular distributions for incident C+60 and C 2+ 60 projectiles, which reflect changes in the interaction potentials at the instants of electron transfers. These distances are consistent with classical over-the-barrier model results indicating that the suppression of charge transfer – observed for atomic projectiles in front of metal surfaces with a projected band gap – is absent for fullerenes.

بررسی ساختار نواری بلور حالت جامد 60 fcc-C
We studied the architecture of the C60 cluster to drive its atomic positions which can be seen at room temperature. We then used the obtained carbon positions as a basis set for the fcc structure to construct the fcc-C60 compound. Self consistent calculations were performed based on the density functional theory (DFT) utilizing the accurate WIEN2K code to solve the single-particle Kohen-Sham eq...
متن کاملElectronic Structures in C 60 -polymers
Variations in the band structures of C60-polymers are studied, when conjugation conditions and the electron number are changed. We use a semiempirical model with the Su-Schrieffer-Heeger type electron-phonon interactions. In the neutral onedimensional C60-polymer, electronic structures change among direct-gap insulators and the metal, depending on the degree of conjugations. High pressure exper...
متن کاملInfluence of surface band gaps on the lifetimes of charge transfer states
Using a first principles electronic structure method, we investigate how a band gap in the surface projected density of states of a noble metal influences the resonant tunneling lifetime of an atomic level near the surface. Comparing Li atoms outside Cu(111), where the Li 2s level is within the gap, with Cu(001), where the Li 2s level is below the gap, reveals that the lifetime of the ionizatio...
متن کاملWave packet propagation study of the charge transfer interaction in the F − – Cu ( 111 ) and – Ag ( 111 ) systems
The electron transfer between an F − ion and Cu(111) and Ag(111) surfaces is studied by the wave packet propagation method in order to determine specifics of the charge transfer interaction between the negative ion and the metal surface due to the projected band gap. A new modeling of the F − ion is developed that allows one to take into account the six quasi-equivalent electrons of F − which a...
متن کاملMetal-insulator transition in C60 polymers.
Variations in the band structures of C60-polymers are studied, when π-conjugation conditions are changed. We look at band structures in order to discuss a metal-insulator transition, using a semi-empirical model with the Su-SchriefferHeeger type electron-phonon interactions. We find that electronic structures change among direct-gap insulators and the metal, depending on the degree of π-conjuga...
