My group is working to theoretically and computationally investigate the nonlinear and quantum behaviour of electrons and photons in semiconductor nanostructures on very short time scales.  Semiconductor nanostructures are semiconductors that are structured on length scales ranging from one to 500 billionths of a metre.  The small size of these structures strongly affects the behaviour of both electrons and photons in the system. The confinement of the electrons results in quantum mechanical effects similar to those that cause energy-level quantization in an atom. In addition, the reflections of the photons at interfaces in a particular type of nanostructure called a photonic crystal can trap the photons, resulting in large changes in the interactions between photons and electrons in the structure.  Due to the combination of electron and photon confinement, the optical and electrical properties of nanostructures are very different than those of the constituent materials.  The careful design and exploitation of confinement-induced effects in nanostructures can produce systems that can be used in a wide variety of applications and devices.

我的团队致力于在很短的时间尺度上从理论和计算上研究半导体纳米结构中电子和光子的非线性和量子行为。半导体纳米结构是一种半导体，其长度范围从千分之一米到500亿分之一米不等。这些结构的小尺寸强烈地影响着系统中电子和光子的行为。电子的限制导致了类似于在原子中引起能级量子化的量子力学效应。此外，光子在一种特殊类型的纳米结构(称为光子晶体)的界面上的反射可以捕获光子，导致结构中光子和电子之间的相互作用发生很大变化。由于电子和光子的结合，纳米结构的光学和电学性质与组成材料的光学和电学性质有很大的不同。仔细设计和利用纳米结构中的限制诱导效应可以制造出可用于各种应用和设备的系统。
