| Abstract: | There are three types of photoexcitation-photoemission processes for electron-holes in the photoluminescence from silicon-rich silicon nitride thin films.In this paper,based on the comparative analysis of the numerical simulation of photoluminescence mechanism models for siliconrich silicon nitride thin films,we suggest that photoluminescence of silicon-rich silicon nitride thin films is a result of the quantum confinement model photoluminescence mechanism and the energy gap states model photoluminescence mechanism operating together,and use the obtained conclusion we discuss some photoluminescence experimental results reported about silicon-rich silicon nitride thin films. |
