Abstract
The microstructure of luminescent porous silicon, formed by electrochemical etching of silicon wafers has been characterized by cross-sectional high-resolution transmission electron microscopy. Results of this study reveal the structure to consist of Si crystallites. The crystallites are ∼3.5 nm in size and are randomly distributed throughout the porous Si region.Keywords
