Quantum Size Effect of Semiconductor Microcrystallites Doped in SiO2-Glass Thin Films Prepared by Rf-Sputtering

摘要: Semiconductors such as CdTe, CdSe and GaAs, microcrystallites could be successfully doped into SiO2-glass films by the magnetron rf-sputtering technique. The average size of depended on sputtering conditions, postannealing was not necessary to form in silica-glass films. diameter varied from below 15 A 62 A. In optical absorption spectra, edge clearly exhibited blue shift compared each bulk semiconductor, thus quantum effect found these microcrystallites.
