- 1. Phys. Rev. B 75, 085423 (2007) , “Room-temperature atmospheric oxidation of Si nanocrystals after HF etching”, X. D. Pi, L. Mangolini, S. A. Campbell, and U. KortshagenThe effect of HF etching of the silicon oxide shell covering the surface of Si nanocrystals (NCs) on the subsequent room-temperature atmospheric oxidation of Si-NCs has been investigated by means of photoluminescence measurements, Fourier transform infrared spectroscopy, and electron paramagnetic...

- 2. Appl. Phys. Lett. 89, 041916 (2006) , “Photoluminescence evaluation of defects generated during SiGe-on-insulator virtual substrate fabrication: Temperature ramping process”, Dong Wang, Seiichiro Ii, Hiroshi Nakashima, Ken-ichi Ikeda, Hideharu Nakashima, Koji Matsumoto, and Masahiko NakamaeCrystal qualities of Si/SiGe/Si-on-insulator structures with different SiGe thicknesses were evaluated by photoluminescence (PL). The wafers were annealed at different temperatures with a ramping rate of 5 °C/min. Free exciton PL peaks were clearly observed for the as-grown wafers and decreased... (Read more)

Kushnirenko, V. S. Lysenko, A. N. Nazarov, A. V. Rusavsky, and S. AshokHydrogenated amorphous silicon carbide (a-SiC:H) films have been deposited using magnetron sputtering technique. An integrated investigation of the effect of vacuum annealing temperature on photoluminescence properties and paramagnetic defects and its correlation with structural... (Read more)

Solids 239, 16-48 (1998) , “Optically active oxygen-deficiency-related centers in amorphous silicon dioxide”, Linards SkujaThe spectroscopic properties, structure and interconversions of optically active oxygen-deficiency-related point defects in vitreous silica are reviewed. These defects, the E′-centers (oxygen vacancies with a trapped hole or 3-fold-coordinated silicons), different variants of diamagnetic...
