[/b]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.

Cluster science is devoted to understanding the changes in fundamental properties of materials as a function of the size, evolving from isolated atoms or small molecules to a bulk phase. In the case of semiconductors, this evolution is remarkable (1). For example, the band gap in CdS can be tuned between 4.5 and 2.5 eV as the size is varied from the molecular regime to the macroscopic crystal, and the radiative lifetime for the lowest allowed optical excitation ranges from tens of picoseconds to several nanoseconds (2). The energy above the band gap required to add an excess charge decreases by 0.5 eV (3). The melting temperature increases from 4000 to 1600°C (4), and the  ressure required to induce transformation from a four- to a six-coordinate phase decreases。。。。。。

如需要我有电子版,因为太大不符合附件要求,没能够上传,可以给我饿email,我发给大家,这期science有很多关于clusters的评述,很有意义!

哈哈,终于能够让大家下载了,但是不知道怎么加密.
