Results of a first investigation of the response of gallium nitride nanowires to high-Z heavy ion irradiation are reported. Pre-irradiation characterization of the gallium nitride nanowires used in these experiments showed that that they had a two-ph

We present a volumetric method for accurate determination of bulk density of aerogels, calculated from extrapolated weight of the dry pure solid and volume estimates based on the Archimedes' principle of volume displacement, using packed 100 μm-size

In this letter, we examine the feasibility of applying positron annihilation spectroscopy to the study of hydrogenized amorphous silicon (a-Si:H)-based structures produced by chemical vapor deposition techniques. The positron probe, sensitive to open

The various techniques of positron annihilation spectroscopy (PAS) may be among the best for characterizing pore size, pore distribution and interconnectivity in amorphous thin films. In particular, PAS is becoming recognized as a practical character

Oxygen radicals (ORs) are highly efficient for in situ cleaning of organic contaminants from the interior of vacuum systems and sample surfaces [1]. ORs decompose organics into gasses (H2O, CO, CO2), which are evacuated from the system. This phenomen

Heavy ion irradiations of single and multi walled carbon nanotubes and total ionization dose of gallium nitride nanowires were investigated. Post irradiation analyses of samples were performed with transmission and scanning electron microscopy, atomi
