Fabrication of InAs Wires in Nanochannel Glass

Indium arsenide wires have been fabricated in a glass host consisting of a high density array of uniformly shaped channels in a matrix glass. Reactions between organoindium compounds and arsine have produced polycrystalline InAs with crystallite sizes of approximately 10 nanometers when annealed at 400°C. At higher annealing temperatures, the wires exhibit an increase in surface porosity and grain size.
