Abstract:
1. Apparatus for producing nanometer-scale patterning on the surface of a sample, comprising: a light source for generating a coherent light beam having a chosen wavelength a focusing optic into which the light beam from said light source is directed, for causing the light beam emerging therefrom to converge; and a Talbot mask having a periodic pattern of nanometer-scale unit cells formed thereon, said Talbot mask disposed in the converging light beam from said focusing optic at a first chosen distance from said focusing optic such that the converging light beam passes therethrough; the sample being disposed at a second chosen distance from said Talbot mask and having a photosensitive surface thereon responsive to the light beam passing through said Talbot mask, for generating a nanostructure having the pattern of unit cells of said Talbot mask on said sample.
