Light-induced directed self-assembly of periodic sub-wavelength nanostructures

A method for the light-induced directed self-assembly of periodic sub-wavelength nanostructures, comprising:

• providing a light source for delivering a beam of photons;
• providing a reaction chamber disposed adjacent to the light source;
• providing a gas comprising one or more precursor materials disposed within the reaction chamber;
• and
• providing a substrate disposed within the reaction chamber, wherein the substrate is positioned and configured to receive the beam of photons;
• wherein the beam of photons causes a periodic sub-wavelength nanostructure of one or more constituents of the one or more precursor materials to form on a surface of the substrate.

A periodic sub-wavelength nanostructure formed by the process comprising:

• providing a light source for delivering a beam of photons;
• providing a reaction chamber disposed adjacent to the light source;
• providing a gas comprising one or more precursor materials disposed within the reaction chamber;
• and
• providing a substrate disposed within the reaction chamber, wherein the substrate is positioned and configured to receive the beam of photons;
• wherein the beam of photons causes the periodic sub-wavelength nanostructure of one or more constituents of the one or more precursor materials to form on a surface of the substrate.
