Vibrational spectroscopic observation of ice dewetting on MgO(001).

The properties of the interfacial water monolayer on MgO(001) during growth of multilayer ice and, in particular, the dewetting of crystalline ice on MgO(001) are revealed by vibrational sum frequency generation and infrared reflection absorption spectroscopy.

Ab initio statistical mechanics of surface adsorption and desorption. I. H2O on MgO (001) at low coverage.

We present a general computational scheme based on molecular dynamics (MD) simulation for calculating the chemical potential of adsorbed molecules in thermal equilibrium on the surface of a material. The scheme is based on the calculation of the mean force in MD simulations in which the height of a chosen molecule above the surface is constrained and subsequent integration of the mean force to ...

An electron-stimulated desorption ion angular distribution and low-energy electron diffraction investigation of CF3I on Ru(001)

We have investigated the structures of CF3I, and its dissociation products, adsorbed on Ru(001) using lowenergy electron diffraction and electron-stimulated desorption ion angular distribution (ESDIAD). Atomic iodine forms (√3x√3)R30° islands even at very low coverages. At 70% of saturation and above, a (2X2) superstructure forms which we attribute to a p(2X2) unit cell with one CF3 group ...

Epitaxial Ag(001) grown on MgO(001) and TiN(001): Twinning, surface morphology, and electron surface scattering

Epitaxial Ag(001) layers were deposited on MgO(001) in order to study electron surface scattering. X-ray reflection indicates 3D layer nucleation with a high rms surface roughness of 1.0 nm for a layer thickness d1⁄4 3.5 nm. X-ray diffraction shows that f111g twins form at d< 11 nm, followed by 2nd generation twinning for 11 nm< d< 120 nm. Increasing the growth temperature from 25 to 150 C supp...

Effect of the cluster size in modeling the H2 desorption and dissociative adsorption on Si„001..

Three different clusters, Si9H12 , Si15H16 , and Si21H20 , are used in density-functional theory calculations in conjunction with ab initio pseudopotentials to study how the energetics of H2 dissociative adsorption on and associative desorption from Si~001! depends on the cluster size. The results are compared to five-layer slab calculations using the same pseudopotentials and high quality plan...
