Size Effect in Silicon Irradiated with Self Ions

Nano- i Mikrosistemnaya Tehnika, 2021
The influence of the thickness of a silicon sample irradiated by silicon ions on the spatial distribution of primary structural defects, phonons, and induced charges is considered. The calculations were performed using the SRIM2013program. The results can be used to analyze the interaction of other types of radiation with silicon wafers, in particular ...

Microstructural Evolution of Self-Ion Irradiation HT9

Volume 1: Plant Operations, Maintenance, Engineering, Modifications, Life Cycle and Balance of Plant; Nuclear Fuel and Materials; Radiation Protection and Nuclear Technology Applications, 2013
Ferritic/martensitic steels are candidates for fast reactors because of their sodium compatibility, superior resistance to corrosion and radiation damage, including swelling, and excellent thermal conductivity and thermal expansion coefficient. One significant limitation of any cladding material is its susceptibility to swelling at high doses.

Effect of irradiation mode on the microstructure of self-ion irradiated ferritic-martensitic alloys

Journal of Nuclear Materials, 2015
Abstract The microstructures of ferritic-martensitic alloys HT9 and T91 were characterized following 5 MeV Fe ++ ion irradiation to 140 displacements per atom (dpa) at 440 °C with either a raster-scanned or defocused beam. Alloys were pre-implanted with 0–100 appm He and then subjected to either a raster-scanned beam or a defocused beam. Relative to

Secondary defect formation in self-ion irradiated silicon

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1995
Abstract A detailed experimental study has been made of the evolution of extended secondary decondary defects which form during rapid thermal anneals of 0.5 MeV energy self-ion irradiated silicon. The implant fluence (2 × 10 15 ions/cm 2 ), flux and substrate temperature (91°C) were chosen so that primary damage levels were well below saturation ...

Order-disorder transformations in Ni4Mo under self ion irradiation

Acta Metallurgica et Materialia, 1995
Abstract The order-disorder transformation has been studied in Ni 4 Mo under cascade forming 300 keV Ni + ion irradiation in the temperature range 300–1050 K. The progressive changes in the short range ordered (SRO) and the long range ordered (LRO) structures and the steady state structures developed at different temperatures have been characterized

Defect clusters and annealing in self-ion-irradiated nickel

Journal of Applied Physics, 1977
Transmission electron microscopy and x-ray diffuse scattering have been used to study defect clusters in 4-MeV self-ion-irradiated (total doses of 2.5×1013 and 5.0×1013 ions/cm2) nickel. The distribution of defect clusters as a function of the ion penetration depth was measured directly in the electron microscope using a transverse sectioning technique.

Influence of irradiation temperature on self-ion damage in copper

The Philosophical Magazine: A Journal of Theoretical Experimental and Applied Physics, 1976
The damage structure produced in copper crystals by irradiation with 30 keV self ions in the temperature range 20°-425°C has been studied by means of transmission electron microscopy.

Effect of irradiation temperature on microstructural changes in self-ion irradiated austenitic stainless steel

Journal of Nuclear Materials, 2017
Abstract We investigated the microstructural and hardness changes in austenitic stainless steel after Fe ion irradiation at 400, 300, and 200 °C using transmission electron microscopy (TEM) and nanoindentation. The size of the Frank loops increased and the density decreased with increasing irradiation temperature.

Annealing studyof self-ion-irradiated gold by proton channeling

Radiation Effects, 1976
Abstract The isochronal annealing of self-ion damage in gold, introduced at room temperature, was measured by the channeling-backscattering method. The results are compared with those obtained from transmission-electron microscope (TEM) observations on similar specimens.

Properties of Self-Ion Irradiated Thin Films

Physica Status Solidi (a), 1971
Thin films vacuum deposited under simultaneous self-ion irradiation show strong crosslink with the substrate, bulk-like properties with enhanced oriented structure, caused by internal electric microfields during island formation, and a constant concentration of radiation damage mainly of the vacancy type.
