Description:Nanochannel glass materials are complex glass structures containing large numbers of parallel hollow channels. In its simplest form, the hollow channels are arranged in geometric arrays with packing densities as great as 1011 channels/cm2. Channel dimensions are controllable from microns to tens of nanometers, while retaining excellent channel uniformity. Exact replicas of the channel glass can be made from a variety of materials. This is a low cost method for creating identical structures with nanoscale features in large numbers.
- High density of uniform channels with diameters from 15 microns to 15 nanometers
- Rigid structures with serviceable temperatures to at least 300deg C, with potential up to 1000deg C
- Optically transparent photonic structures with high degree of reproducibility
- Filters for particle sizing for monodispersion of particle sizes
- Material for chromatographic columns
- Unidirectional conductors
- Nonlinear optical devices
- Masks for semiconductor development, including ion implantation, optical lithography, and reactive ion etching.
