【求助】求助，关于量子点定义
|
|
|
谁能帮忙找篇关于量子点由来，定义的综述。当然如果能介绍量子点发展现状的更好。 [ Last edited by wdwsnnu on 2009-10-13 at 13:33 ] |

Quantum dots (QDs), also called as nanocrystals, are a special class of semiconductor crystals which are compose of periodic groups of II-VI, III-V, or IV-IV materials, such as CdSe (Lee et al., 1998; Strassburg et al., 2000; Kratzert et al., 2001), InAs (Ebiko et al., 1998, 1999; Nakata et al., 2000; Márquez et al., 2001; Joyce et al., 2001; Yamaguchi et al., 2000; Migliorato et al., 2002; Krzyzewski etal., 2002; Wasserman et al., 2003; Bester et al., 2003), InP (Seifert et al., 1996; Schmidbauer et al., 2002; Persson et al., 2003) and Ge QDs (Eaglesham et al., 1990; Liu et al., 1997; Kamins et al., 1997; Ross et al., 1998; Ribeiro et al., 1998; Vailionis et al., 2000; Liu et al., 2000; Denker et al., 2001; Tersoff et al., 2002; Rastelli et al., 2002, 2003; ). Semiconductors derive their great importance from the fact that their electrical conductivity can be altered by adding an external stimulus, such as voltage. Therefore, semiconductors can be used to make critical parts of many different kinds of electrical circuits and optical applications. Semiconductor QDs, as a special structure, have their name because their small size causes quantum confinement and creates specific electronic states (Reithmaier et al., 2004; Badolato et al., 2005; Xu et al., 2007). Due to the quantum confinement and specific electronic states, QDs enable never before seen applications to science and technology. 自己以前写的，仅供参考 |
