A combination of both Raman and Brillouin scattering experiments as well as Molecular Dynamics (MD) was used to study the superionic behaviour of BaF2 doped with a wide range of LaF3 concentrations (0 ⩽ x ⩽ 50 mol%). Raman spectroscopy reveals th

Nanocrystals of Al and Y co-doped SnO2 were successfully synthesized using the sol–gel method. The samples were subjected to different temperatures ranging from 200 to 1,000 °C. The effects of Al and Y combinational doping and temperature on the s

High temperature Brillouin and Raman light scattering studies have been used to study the transition to the superionic state of CaF2 (10 mol%LaF3) and CaF2 (10 mol%TbF3) over the range 300 to 1200 K. The Brillouin scattering results yield the tempera

High temperature Raman and Brillouin light scattering experiments have been combined with molecular dynamics simulations to provide a comprehensive study of the superionic state of BaF 2 ( x v mol% LaF 3 ) over a particularly wide range of LaF 3 dopa

In this study we investigate the superionic behaviour in Ba1-xLaxF2+x (x = 0.2, 0.3 and 0.5, respectively) over a range of temperatures using Raman scattering. The line-widths of the Raman peaks show a linear increase with temperature but above a cer

Different forms of tin-dioxide (SnO2) ceramic have been thoroughly studied in recent years because of its potential in sensing and fuel cells. The current findings used classical molecular dynamics simulations focused on the role of defects in tin-di
A problem in the study of nanoparticles is that they will tend to grow at moderate temperatures. For example, most oxides (e.g. SnO2, ZrO2, MgO) will show significant grain growth at 400degreesC. This severely limits experimental studies that require

The squares of the Brillouin frequencies (ΔωB)2 of the LA mode in the [100] direction related to the C11 elastic constant show a linear decrease with temperature followed by significant deviations that occur above the corresponding transition tempe
