A range-energy table for heavy particles in silicon

Range Distributions of Low-energy Nitrogen and Oxygen Ions in Silicon (RESEARCH NOTE)

The range distributions of low-energy nitrogen and oxygen (2-3 keV) ions is silicon are measured and compared with these available in theories. The nitrogen distribution is very close to a Gaussian distribution as predicted by theory. The oxygen profile however, indicates a surface localized peak along with a shoulder and a long tail into the sample. The surface peak is beleived to he the resul...

Energy Loss in Matter by Heavy Particles

An approximate analytical solution of the Bethe equation for charged particles in the range of radiotherapy energy

Charged particles such as protons and carbon ions are an increasing tool in radiation therapy. However, unresolved physical problems prevent optimal performance, including estimating the deposited dose in non-homogeneous tissue, is an essential aspect of optimizing treatment. The Monte Carlo (MC) method can be used to estimate the amount of radiation, but, this powerful computing operation is v...

Defect Generation in Crystalline Silicon Irradiated with High Energy Particles

High resistivity silicon with different concentrations of the impurities oxygen and carbon were irradiated with neutrons and charged particles. The DLTS method is used to determine the defect parameters. During irradiation of silicon with particles lattice atoms are displaced and the primary defects silicon interstitials and vacancies form the impurity defects Ci, CiCs, CiOi and V Oi. In the de...
