The Physical and Optical Properties of Self-Assembled Si Nanocrystals

纳米材料的性质可能与其大块材料的性质有很大不同。因此，它们可以提供具有新的和新颖的性质的材料，以及证明现代理论的有用测试。这种效应的重要性的一个突出例子是量子受限硅结构，例如多孔硅或纳米晶硅，它们的发光效率比体硅高出一百万倍。该项目旨在了解支持这种具有重要技术意义的材料潜在应用的新的光学特性和相互作用。

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.
