%X Porous silicon is one of attractive light-emitting materials nowadays. The advantage of silicon-related light emitting materials is an environmental-friendly property and low cost of the material. Light-emitting porous silicon has extensively been studied for more than twenty years, mainly being formed on a p-type silicon wafer. The n-type silicon is also of importance because the pn junction, made of the two types of silicon, is a key structure for electronic devices. This article reports the formation of porous silicon formed on n-type silicon wafers and shows the surface and cross-sectional structures observed by a scanning electron microscope. The formation characteristics of porous silicon on n-type silicon wafers are discussed.
