Porous Silicon: From Luminescence to LEDs

JAN 01, 1997

With its tunable light emission, room‐temperature quantum efficiencies near 10% and increasingly efficient light‐emitting diodes, porous silicon may hold the promise of fully integrated optoelectronic devices.

Silicon is at the heart of the microelectronics revolution. Its dominance over other semiconductors is intimately tied to its superior materials and processing properties and to the tremendous base of technology that has developed around it. Another semiconductor is not likely to displace silicon as the material of choice in electronic applications. Silicon, however, is an extremely inefficient light emitter, and for this reason has not enjoyed the same level of dominance in optical applications.
