目前对半导体团簇的研究主要集中在量子点的性质上，量子点是由数百到数千个原子组成的半导体碎片，具有体成键几何形状，并通过在具有较大带隙的材料中封闭而消除表面态。量子点表现出强烈依赖于尺寸的光学和电学性质。将这些点连接成复杂集合的能力为科学发现创造了许多机会。
Current research into semiconductor clusters is focused on the properties of quantum dots-fragments of semiconductor consisting of hundreds to many thousands of atoms-with the bulk bonding geometry and with surface states eliminated by enclosure in a material that has a larger band gap. Quantum dots exhibit strongly size-dependent optical and electrical properties. The ability to join the dots into complex assemblies creates many opportunities for scientific discovery.
