SRIM/TRIM SIMULATION OF ION-BEAM MODIFICATION OF ZrO2 - BASED CERAMIC MEMBRANES WITH Ag AND Au IONS

Implantation of 50–2000 keV silver and gold ions into zirconiabased ceramic membranes was simulated by the Monte Carlo method in the binary collision approximation on the physical basis of SRIM/TRIM. Stopping powers, projected ranges (19–338 nm for Ag and 16–231 nm for Au), vacancies per ion (up to...

ANALYSIS OF STRUCTURAL CHANGES IN NEODYMIUM -DOPED SILICON BY RAMAN SPECTROSCOPY

In this work, structural changes arising from the doping of p-type silicon (KDB-48, ρ=48 Ω·cm) single crystals with neodymium (Nd) atoms by thermal diffusion were studied using Raman spectroscopy. Samples were diffused in vacuum quartz ampoules at 1300o C for 10 hours and prepared by rapid cooling....
