Self-assembled nanostructure

These self-assembled structures are used to make arrays of gold and silver nano-pyramids. Such nano-pyramid arrays couple laser light into surface plasmons, which we have shown results in the emission of a burst of electricity and the subsequent emission of terahertz radiation.
