Annotation:
Secondary ion mass spectrometry (SIMS) is a surface analysis technique capable of providing isotopic and molecular information. SIMS uses keV projectiles to impinge upon a sample resulting in secondary ion emission from nanometric dimensions. It is well documented that secondary ion emission is enhanced using cluster projectiles compared to atomic projectiles. Previous studies of enhanced secondary ion yields with cluster projectiles have led to the present study dealing with the scope of C60 as a projectile for SIMS.

Annotation:
Nearly all the deficiencies of conventional vacuum evaporated coatings trace to a single physical property of condensed films: low packing density. One way to increase packing density is to bombard the growing film with ions during deposition, called ion-assisted deposition (IAD). The beginning chapters of this dissertation analyze IAD as a perturbation of the conventional vacuum evaporation process. The experimental chapters begin with an examination of the effect on moisture penetration behavior of oxygen-ion bombarding completed optical filters. Moisture adsorption and desorption is retarde

An experimental and theoretical analysis of the effects of ion bombardment on Schottky diodes is presented. The experimentally observed shifts in diode performance are compared to the conditions of ion exposure. These experiments show that Schottky diodes exposed to ion beams show decreases in effective barrier heights and ideality factors, as well as increased incidence of premature reverse breakdown. The change in barrier height is found to be proportional to the energy of the individual ions and the total number of ions delivered to the surface. A numerical simulation of the damage process

It was proposed that amorphous alloys may be more resistant to radiation damage than crystalline metals. In crystalline metals neutron induced transmutations lead to the formation of inert gas bubbles. These preferentially nucleate near line defects and result in embrittlement. Amorphous alloys do not contain sites where nucleation can occur preferentially. In this work the growth of argon bubbles in amorphous Cu[50]Zr[50] has been induced by implanting thin specimens with 80keV argon ions at room temperature. The bubble size distribution was obtained over the dose range 5x10[16] to 3x10[17] A

This thesis is concerned with the formation, characterisation and application of doped surface layers in hydrogenated amorphous silicon, a-Si:H. In this study, a-Si:H films have been deposited using a plasma enhanced chemical vapour deposition (PECVD) system and have been doped using ion implantation. In order to determine the efficiency of implantation doping various ion species, ion doses, and ion energies were made by direct implantation of impurities at low energies. Coupled with the annealing effect, the effect of doping on damage recovery has been studied. It has been shown that there is

Beginning with its emergence from a high-aspect ratio rectangular aperture, the physics of an intense (current density ≳ 1 mA/cm²), positively charged ion beam is explored in two distinct regions: an electron-free drift region, and a beam plasma containing a large density of space-charge neutralizing electrons. In the drift region, the beam expands due to the mutual inter-ion Coulomb repulsion. Energy, mass, and phase-space density conservation are combined with Poisson's equation to obtain the beam ion density and resulting potential of the diverging beam at any point in 3-dimensional space.

The effects of ion bombardment on the chemical reactivity of GaAs(100) were investigated by X-ray photoelectron spectroscopy.
