Semiconductor nanostructures are interesting from a standpoint of fundamental science and compelling for their promise in a wide variety of applications. These materials are in a size regime between molecules and bulk solids. One can therefore tune the electronic and optical properties of these materials by physical confinement of the charge carriers. The objective of this proposal is to investigate the dynamics of charge carriers in colloidal quantum confined semiconductor nanostructures. The outcome will be an understanding of the factors that govern the properties of nanostructures, enabling rational implementation of nanomaterials into new devices.

从基础科学的角度来看，半导体纳米结构是有趣的，并且由于其在各种应用中的前景而引人注目。这些材料的尺寸范围介于分子和大块固体之间。因此，人们可以通过对电荷载流子的物理限制来调整这些材料的电子和光学性质。本计画的目的是研究胶体量子限制半导体奈米结构中的载子动力学。其结果将是对控制纳米结构特性的因素的理解，从而使纳米材料能够合理地应用于新设备。
