Claims37
A light emitting device comprising:
- a silicon substrate at least a portion of which comprises porous silicon, said porous silicon having a porosity of at least 60% and incorporating silicon quantum wires;
- and
- means for exciting said porous silicon to emit light.
A light emitting device comprising:
- a silicon substrate at least a portion of which comprises porous silicon, said porous silicon having a porosity of at least 60% and incorporating silicon quantum wires, said porous silicon made by the steps of:
- anodizing said portion of said silicon substrate to produce a porous layer thereon;
- and
- etching said porous layer sufficiently so as to produce pore overlap and thereby defining discrete quantum wires;
- and
- means for exciting said porous silicon to emit light.
