First-principles study on field evaporation of surface atoms from W(011) and Mo(011) surfaces
The simulations of field-evaporation processes for surface atoms on W(011) and Mo(011) surfaces are implemented using first-principles calculations based on the real-space finite-difference method. The threshold values of the external electric field for evaporation of the surface atoms, which are ∼ 6 V/Å for tungsten and ∼ 5 V/Å for molybdenum, are in agreement with the experimental results. Wh...
متن کاملField-evaporation from first-principles
Under the application of a strong electric field, atoms from a metal surface can rupture their bonds and escape, leading to ‘field-evaporation’. We present a firstprinciples description of this phenomenon, taking as an example the evaporation of Al adatoms from an Al(111) surface. The ‘charged-plane’ method [A.Y. Lozovoi and A. Alavi, Phys Rev B 68, 246416 (2003)], has been implemented in the c...
متن کاملFacile abstraction of hydrogen atoms from graphane, diamond, and amorphous carbon surfaces: A first-principles study
ion of surface hydrogen by atomic H from graphane, diamond 001 , diamond 111 , and hydrogenated amorphous carbon a-C:H surfaces was studied using density-functional theory calculations in the generalized gradient approximation. Our calculations show that for each surface, the abstraction reaction is highly exothermic with a negligible activation energy barrier. The degree of exothermicity depen...
متن کاملeffects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
15 صفحه اولFirst-principles calculation of field emission from metal surfaces
The field-emission current from realistic metal surfaces is evaluated within the density-functional theory using the Landauer-Büttiker approach. The electronic density in the surface region and the potential barrier induced by the finite electric field are calculated self-consistently using a Green’s-function embedding scheme and the full-potential linearized-augmented plane-wave method. Applic...
