Reports that a team from the electronics division of Great Britain's Defense Research Agency in Malvern, led by Leigh Canham, has presented results of study which showed that porous silicon has emitted light when an electric current was passed through it, at a meeting of the Materials Research Society in Anaheim, California. Colors produced by the porous silicon; Benefits of making optical emitters, waveguides and detector out of silicon; Etching technique for the surface of a silicon wafer.
