چکیده

Chloropentane forms asymmetric ('A') and symmetric ('S') pairs on Si(100)-2×1, differing in the direction of curvature of one pentane tail. Surprisingly this renders the rate of thermal reaction of 'A' fifteen times greater than 'S' in chlorinating room-temperature silicon. Correspondingly, for electron-induced reaction the energy threshold for A is 1 eV less than for S.

Imprinting self-assembled patterns of lines at a semiconductor surface, using heat, light, or electrons.

The fabrication of nano devices at surfaces makes conflicting demands of mobility for self-assembly (SA) and immobility for permanence. The solution proposed in earlier work from this laboratory involved pattern formation in physisorbed molecules by SA, followed by localized reaction to chemically imprint the pattern substantially unchanged, a procedure we termed molecular-scale imprinting (MSI...

Adsorption of Acetylene on Si(100)-(2 × 1)

A study of a single acetylene adsorbed onto the Si(100)-(2×1) surface is presented. A MCSCF+MRMP2 wave function is used to study this system, which is shown to be significantly multiconfigurational over large sections of the potential energy surface. The lowest energy isomer is shown to have the acetylene adsorbed directly above a single dimer, di-σ, where the silicon−silicon dimer bond remains...

Calculation of desorption and migration of hydrogen on SiGe(100)-2×1 surface using density functional theory

Ab initio calculations have been carried out to investigate the H-atom migration and H2 desorption on the mixed SiGe(100)-2×1 surface using the Si9-xGexH13, Si14GeH19 and Si13Ge2H19 cluster models. The H2 recombinative desorption is the rate-determining step in hydrogen migration and desorption on SiGe(100) surface since the energy barrier of H-atom migration is generally lower than that of H2 ...

The isomeric effect on the adjacent Si dimer didechlorination of trans and iso-dichloroethylene on Si(100)-2×1.

The dechlorination processes of isomers trans and iso-dichloroethylene (iso-DCE) on Si(100)-2×1 were investigated from first principles, to ascertain the isomeric effect on the adjacent Si dimer di-dechlorination of DCE on Si(100)-2×1. By comparing the feasible adspecies and their reaction barriers between trans and cis-DCE on Si(100)-2×1, we found that the isomeric effect of trans-DCE is negli...

Surface behavior of amphiphiles in aqueous solution: a comparison between different pentanol isomers.

Position isomerism is ubiquitous in atmospheric oxidation reactions. Therefore, we have compared surface-active oxygenated amphiphilic isomers (1- and 3-pentanol) at the aqueous surface with surface- and chemically sensitive X-ray photoelectron spectroscopy (XPS), which reveals information about the surface structure on a molecular level. The experimental data are complemented with molecular dy...
