Many metal alloys are susceptible to corrosion, particularly after processing steps such as welding. Chemical vapor deposition (CVD) is an effective way to modify metal surfaces and impart specific physical and chemical properties. A hydrophobic, nan

Reflection-absorption infrared spectroscopy of the model interface derived from H(10)Si(10)O(15) on Si(100)-2x1 is presented. The spectra obtained are compared to the H(8)Si(8)O(12)-derived model interface and discussed in terms of the soft X-ray pho

Hydridosilsesquioxane-based model systems have been developed over the past five years to help elucidate the structure and reactivity properties of silicon/silicon oxide interfaces. In this paper, the assignment of infrared bands as Si−O or Si−H

The observed binding energy shift for silicon oxide films grown on crystalline silicon varies as a function of film thickness. The physical basis of this shift has previously been ascribed to a variety of initial state effects (Si–O ring size, stra

Recently reported molecular ion/surface scattering experiments suggest that translational and vibrational energies each have a distinct influence on molecular dissociation for the NO+/GaAs(110) system [J. Chem. Phys. 1994, 100, 6791]. To interrogate

The processes of electron transfer and dissociative scattering are explored for collisions of hyperthermal NO + on GaAs(110). The experiments reveal a marked angular dependence to O − emergence. A strong correlation between the O − scattering ang

Hyperthermal energy reactions of NO+ with Ag(111) were studied as a function of collision energy and the incident diatom’s internuclear‐axis direction. Laser photoselection via (1+1’) resonance enhanced multiphoton ionization (REMPI) prepared a

The reactivity of a molecule striking a surface was found to depend on the diatom's internuclear-axis alignment. State-selected NO+ (X1Σ+, v = 0, J) reagents were aligned through laser ionization prior to their impact with a Ag(111) surface. The yie

The scattering of state‐selected NO+(X 1Σ+, v=0–6) on GaAs(110) was explored across the hyperthermal energy region. Relative yields and velocity distributions for scattered anionic products NO−(X 3Σ−, v=0) and O−(2P) were measured as a fu

A hyperthermal beam of state‐selected NO+ X Σ+(v=0–6) ions is scattered on a clean, well‐characterized GaAs(110) surface. The threshold for the appearance of scattered O− ions occurs at a collision energy of 25 eV. Vibrational energy proves
