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 - the nanometer length scale. The novel aspect of nanoscience is that one can use size and geometry to tune the electronic and optical properties of these materials by virtue of physical confinement of the charge carriers. The availability of nanoscale structures opens up a wealth of new physics, chemistry, and materials science.

从基础科学的角度来看，半导体纳米结构令人感兴趣，并因其在广泛的应用中的前景而引人注目。这些材料的大小介于分子和散装固体之间--纳米级。纳米科学的新方面是，人们可以通过电荷载流子的物理限制，利用尺寸和几何形状来调节这些材料的电子和光学性质。纳米级结构的出现开辟了丰富的新物理、化学和材料科学领域。
