| Abstract(in English) | The purpose of this study is the application to nanocrystal memory noticed as a next generation non-volatility memory. We have fabricated germanium (Ge) nanocrystals self-assembled in silicon dioxide (SiO_2) film using electoron-beam vaper depositon, and investigated their crystallinities and optical characteristics. When Ge is deposited on SiO_2 and then heat-treated, it assembles in SiO_2, finally changes to nano-size crystals. The size of Ge nanocrystal obtained in this study was estimated in the range of 5.7 nm from the result of Raman spectroscopy measurement. Defect related emission from the Ge nanocrystals was observed at room temperature in the photoluminescence (PL) measurement. |
