| 中文摘要 | nanocrystalline silicon embedded sio2 matrix has been formed by annealing the a-siox films fabricated by plasma enhanced chemical vapor deposition technique. absorption and photoluminescence spectra of, the films have been studied in conjunction with micro-raman scattering spectra. it is found that absorption presents an exponential dependence of absorption coefficient to photon energy in the range of 1.5-3.0 ev, and a sub-band appears in the range of 1.0-1.5 ev. the exponential absorption is due to the indirect band-to-band transition of electrons in silicon nanocrystallites, while the sub-band absorption is ascribed to transitions between surfaces and/or defect states of the silicon nanocrystallites. the existence of stokes shift between absorption and photoluminescence suggests that the phonon-assisted luminescence would he enhanced due to the quantum confinement effects. |
