Abstract

It is suggested by this investigation, that light emission from Porous Silicon is due to the recombination of excitons generated in different locations. The majority of excitons generate from the nano-size crystalline silicone. However, excitons generated from amorphous silicon/SiO2 interface are also contributing to the whole excitons population in the material. Further, it is suggested that all excitons are confined and recombine in amorphous region.
