The Physical and Optical Properties of Self-Assembled Si Nanocrystals

The properties of nano-scale materials can differ significantly from those of their bulk counterparts. As such, they can provide materials with new and novel properties as well as proving a useful test of modern theories. An outstanding example of the significance of such effects is provided by quantum confined silicon structures, such as porous or nanocrystalline silicon, which exhibit luminescence efficiencies up to a million times greater than bulk silicon. This project aims to understand the novel optical properties and interactions that underpin potential applications of this technologically important material.
