Radiative Recombination at Centres in Germanium-Silicon Solid Solutions

Irradiated Carbon Nanostructures as Nanoscopic Pressure Cells

“…We compare the predictions for this contraction regime with observations of irradiated CO by Banhart and Lyutovic [3,5,19]. In these studies, irradiation was carried out in a 1.2 MeV high-voltage electron microscope with typical beam intensities of 4.5 × 10 5 A/m 2 , corresponding to typical displacement rates of 10 − 2 dpa/s.…”

“…In these studies, irradiation was carried out in a 1.2 MeV high-voltage electron microscope with typical beam intensities of 4.5 × 10 5 A/m 2 , corresponding to typical displacement rates of 10 − 2 dpa/s. Irradiation at temperatures around 1000K induced pronounced compression after doses of a few dpa [19]. Shell radii were determined from electron micrographs by tracing the contrast peak which indicates the location of a shell and determining the enclosed area.…”

“…Empty symbols: R/R0 = 0.9, cross center symbols: R/R0 = 0.6, full symbols: R/R0 = 0.3. Bottom: Contraction of a CO with N = 14 during irradiation at 1000 K with 1.2 MeV e − (flux density 150 A/cm 2 )[19]; the experimental data were taken after irradiation doses of 6dpa, 12dpa and 60dpa; Crosscenter symbols: CO with 28 shells after irradiation under the same conditions to approximately 30 dpa.…”
