EXPERIMENT STUDY OF RELATION BETWEEN POROUS Si LUMINESCENCE AND QUANTUM SIZE EFFECT
Electrochemical etching method was employed to fabricate porous silicon(PS)film.Experiment results showed that PS film had multilayer structures.Surface layer was nanostructure
other layers were μm-structure layers.Study of physical and chemical structure of PS film showed that PS was composed of nanosilicon and μm-silicon wires surrounded by Si.O.H.F compounds.PS luminescence comes from surface nanostructure layer.No light emitted from μm-structure layers.We proved from experiment that PS luminescence was relevant to quantum size effect.
