The characteristics of ion beam assisted etching of GaAs by pulsed focused ion beam irradiation
Microelectronic Engineering, 1993Abstract We investigated the characteristics of ion beam assisted etching of GaAs by continuous and pulsed Ga + beam irradiation in a Cl 2 ambient. A rate equation model was proposed to explain the measured etch yield. By pulsed beam irradiation, the etch yield increased up to 500 atoms/ion and this increase was explained by the accumulation of ...

Mutation induced with ion beam irradiation in rose
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2003Abstract The effects of mutation induction by ion beam irradiation on axillary buds in rose were investigated. Axillary buds were irradiated with carbon and helium ion beams, and the solid mutants emerged after irradiation by repeated cutting back. In helium ion irradiation, mutations were observed in plants derived from 9 buds among 56 irradiated ...

Patterning magnetic films by ion beam irradiation
Journal of Applied Physics, 2000We have used ion beam irradiation through a silicon stencil mask to alter the magnetic properties of Co/Pt multilayer and FePt chemically-ordered superlattice films. In both systems, ion irradiation disorders the as-grown films which results in a reduction of the magnetic anisotropy.

Nano-fabricated cdw by ion-beam irradiation
Synthetic Metals, 1999We propose a new technique of nano size CDW formation by applying two types of accurately controlled ion-beams to one dimensional bulk conductor. The CDW sample has 400 A thickness and 1000 A width. As a result of our investigation, we have found that the nano-fabricated CDW shows collective sliding and negative resistance above some threshold electric

Infrared analysis of ion beam irradiated polymers
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2009Abstract Irradiation with heavy ions can produce several modifications in the chain structure of polymers. These modifications can be related to scissioning and cross-linking of chemical bonds, which depend on the ion fluence and the density of energy deposited in the material. Stacked thin film Makrofol-KG® samples were irradiated with 350 MeV Au26+

Smoothing of Diamond Films by Ion Beam Irradiation
1991Abstract In this paper, smoothing of CVD diamond films by ion beam irradiation has been described. Diamond films are synthesized by arc discharge plasma jet CVD and microwave plasma CVD. As a result, by setting up an incident angle at 0°, 80°, smooth surfaces of microwave plasma CVD diamond films have been obtained.

[Biocompatibility of ePTFE modified by ion beam irradiation].
No shinkei geka. Neurological surgery, 2004Expanded polytetrafluoroethylene (ePTFE) is a stable polymer and widely used as a prosthesis because of its chemical inertness. However, ePTFE as an artificial dura mater is often associated with postoperative leakage of the cerebrospinal fluid (CSF) due to its very low adhesiveness to fibrin glue and surrounding tissue.
