Silicon-based visible light-emitting devices integrated into microelectronic circuits
Article Abstract:
Integration of silicon-based visible light-emitting devices into standard silicon microelectronic circuits has become possible through the use of porous silicon. Partial oxidation improves the chemical and thermal stability of porous silicon without interfering with its charge-transport and light-emitting properties. Porous silicon is efficient, and generates visible photoluminescence and room-temperature. However, it is highly fragile and reactive, and these two properties have so far prevented its integration with silicon processing techniques.

Silicon integrated circuits shine
Article Abstract:
The integration of silicon-based light-emitting diodes with standard bipolar microelectronic circuits will create new vistas for inexpensive optoelectronics. Porous silicon is efficient, and produces photoluminescence and room-temperature. However, it has a short useful lifetime, as it is thermally and chemically unstable. The encapsulation of porous silicon in aluminium oxide and aluminium, and the oxidation of porous silicon surface enhances useful lifetime and speed of response of porous silicon.
