Abstract
The recent demonstrations of visible light emission from porous silicon, both photoluminescence and electroluminescence, have caught the attention of the semiconductor research community. Such silicon‐based light emitting devices have considerable potential in the opto‐electronics industry. This article reviews the present understanding of the electrochemistry of pore formation, the structure, and the light emitting properties of porous silicon.
