The vibrational properties of the three ordered metallic surface alloys, Cu(100) -c(2 × 2)- Pd , Cu(100)-(2 × 1)-Pd , and Cu(100)-(2 × 2)-Pd , are presented. The phonon dispersions of vibrational modes as well as the local density of phonon states (LDOS) are calculated using matching theory associated with Green's function formalism. The calculated results are discussed and interpreted. In particular, the transfer of charge between the Pd and Cu atoms in the surface alloys modifies the surface boundary force constants, with resultant remarkable differences for the vibrational LDOS on the Pd and Cu atomic sites at the Pd/Cu(100) surface, compared to the LDOS at the pure Cu(100) surface. This may favor new Pd -catalyzed reactions at such surface alloys systems.

It has been reported that SiC surface can be etched off in a concentrated aqueous solution of hydrogen fluoride with making contacts with Pt plate catalyst, named Catalyst-referred Etching (CARE) [1]. In this report, we present first-principles molecular-dynamic simulations on the initial stage of the etching process. Reaction barrier heights of dissociative absorption reactions of hydrogen fluoride molecule breaking into back-bonds at step edge of 3C-SiC(111) are analyzed.
