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...

PHASE TRANSFORMATIONS AND X-RAY DIFFRACTION PATTERNS IN THE SI-MN SYSTEM
In this study, the phase composition and crystallization kinetics of a Si-Mn heterosystem synthesized on single-crystal silicon substrates via hightemperature thermal vacuum diffusion were comprehensively investigated as a function of annealing temperature (600-1200o C) using X-ray diffraction...

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....

HYDROTHERMAL SYNTHESIS OF TIO₂ NANOTUBES: EFFECTS OF HCL TREATMENT TIME AND ANNEALING TEMPERATURE ON CRYSTAL STRUCTURE, MORPHOLOGY, AND OPTICAL PROPERTIES
TiO₂ nanotubes structures were synthesized by alkaline hydrothermal treatment of commercial TiO₂ powder, followed by HCl treatment and thermal annealing. The effects of acid-treatment time and annealing temperature on the structural, morphological, and optical properties were investigated by XRD,...
