Titanium-Silicon Interactions During Ion Beam Irradiation

MRS Proceedings, 1986
AbstractAs* ion beam irradiation of thin titanium (∼300Å) films deposited on silicon substrates at sufficiently high dose and energy has been shown to induce an athermal thin film reaction (as evidenced by insenstivity of the reaction to irradiation current) leading to the formation of a homogeneous titanium subsilicide phase with an extremely smooth ...

Cantilever Beam Stress Measurements During Ion Irradiation

MRS Proceedings, 1995
AbstractIn-situ stress measurements on single crystal MgO and A1203 have been performed during ion irradiation. A cantilevered beam sample arrangement was used, with the stress in the implanted layer determined from the deflection of the sample as measured by the change in capacitance between the free end of the sample and a reference electrode.

Low energy ion beam irradiation of silicon

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996
Abstract A focused ion beam system with a liquid metal ion source has been used to irradiate monocrystalline silicon with various ions (Ga, Si, Au, Au clusters) at energies from 60 keV down to 40 eV. The fluence was between 10 12 and 10 16 atoms/cm 2 .

Ion Beam Irradiation Effects on Polymers

MRS Proceedings, 2003
ABSTRACTThe main effects of the interaction of accelerated ions with polymeric targets are critically reviewed. The possibility of a relatively reduced heating of polymer during ion beam bombardment is analyzed. Experimental data pointing towards various radiation-induced modifications in polycarbonate (free radicals production, modifications of the ...

Shattering solids by irradiating supercurrent ion beams

Radiation Effects, 1988
Abstract This paper reports the first experimental results on shattering solids by irradiating supercurrent proton beams. The obtained results have been compared with the data by irradiating pulse supercurrent electron beams and have been discussed. A calculation of the solid dielectric doses by irradiating 14 MeV neutrons has been carried out.

ESR investigations on ion beam irradiated polycarbonate

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1994
Abstract Electron spin resonance (ESR) investigations with a polycarbonate solid state nuclear detector, irradiated with oxygen ions, are reported. The nature of the paramagnetic defects induced by irradiation is discussed. The temperature dependence of resonance line parameters is studied.

Optical absorptivity of ion-beam irradiated silicon

Applied Physics A Solids and Surfaces, 1988
Single-crystal layers of silicon on sapphire have been irradiated with Ne and Kr ions at room temperature. The concomitant changes in optical absorption have been measured as a function of photon energy. The absorptivity of the amorphized silicon is about one order of magnitude higher as compared to the crystalline state in the photon energy interval ...

Ion beam irradiation of polytetrafluroethylene-loaded polyetheretherketone

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006
Experiments were performed to study the radiation tolerance and mechanical stability of polytetrafluoroethylene (PTFE) loaded polyetheretherketone (PEEK) exposed to alpha particle radiation. Accelerator generated alpha beams were used to provide the extreme upper limit for the radiation environment of actinide sources where the polymer is employed in ...

Nitridation of vanadium by ion beam irradiation

Surface and Coatings Technology, 1994
Abstract The nitridation of vanadium by ion beam irradiation is studied by the ion implantation method and the dynamic mixing method. The nitrogen ion implantation was carried out into deposited V(110) films. Using both methods, three phases are formed, i.e. α-V, β -V 2 N, and δ -VN.

Titanium surface after neutralized ion beam irradiation

Vacuum, 2003
One of the most important factors which affect solid surface roughness is an ion incidence angle and glancing-angle irradiation seems to be crucial in surface smoothing. The object of our interest was polycrystalline 99.5% titanium polished by a very inclined neutralized ion beam from the glow discharge (GD) ion gun.
