On the application of periodic quantum wire nanostructures in optical sensors

Periodic nanostructures have been proposed as artificial materials showing unique features. An example of this kind of systems, obtained experimentally, consists on a two-dimensional parallel quantum wire array placed on a similar array turned 90 degrees. In such a way, the crossings of the quantum wires are arranged in two dimensions, and could behave as a quantum dot ordered array. This system is expected to show a particular band structure giving rise to interesting interactions with light that could be useful for development of future generations of optical sensors.
