Nanoclusters

Study of nanoclusters provides insight into the mesoscopic regime between single molecules and bulk crystals. Nanoclusters exhibit strong quantum confinement and surface effects. Using nanoclusters as “building blocks” for novel materials offers an opportunity to understand how atomic structure can lead to physical and chemical properties of macroscopic materials. It is possible to produce Nan clusters with atomic arrangements that do not normally exist in nature, leading to novel optical and magnetic properties. ZnO semiconductor sources ZnO is a wide band gap semiconductor that has attracted tremendous interest as blue light emitting materials, gas sensors and transparent conductors in solar cells. Unlike other semiconductor compounds that contain cadmium, arsenic, or other environmental toxins, zinc and oxygen are “environment friendly” elements. In fact, ZnO is used as a dietary supplement in animal feed. The stability of excitons in ZnO results in a very high quantum efficiency a
