前言

大學(xué)最重要的功能是向社會輸送人才。大學(xué)對于一個國家、民族乃至世界的重要性和貢獻(xiàn)度，很大程度上是通過畢業(yè)生在社會各領(lǐng)域所取得的成就來體現(xiàn)的。中國科學(xué)技術(shù)大學(xué)建校只有短短的50年，之所以迅速成為享有較高國際聲譽(yù)的著名大學(xué)之一，主要就是因為她培養(yǎng)出了一大批德才兼?zhèn)涞膬?yōu)秀畢業(yè)生。他們志向高遠(yuǎn)、基礎(chǔ)扎實、綜合素質(zhì)高、創(chuàng)新能力強(qiáng)，在國內(nèi)外科技、經(jīng)濟(jì)、教育等領(lǐng)域做出了杰出的貢獻(xiàn)，為中國科大贏得了“科技英才的搖籃”的美譽(yù)。2008年9月，胡錦濤總書記為中國科大建校五十周年發(fā)來賀信，信中稱贊說：半個世紀(jì)以來，中國科學(xué)技術(shù)大學(xué)依托中國科學(xué)院，按照全院辦校、所系結(jié)合的方針，弘揚(yáng)紅專并進(jìn)、理實交融的校風(fēng)，努力推進(jìn)教學(xué)和科研工作的改革創(chuàng)新，為黨和國家培養(yǎng)了一大批科技人才，取得了一系列具有世界先進(jìn)水平的原創(chuàng)性科技成果，為推動我國科教事業(yè)發(fā)展和社會主義現(xiàn)代化建設(shè)做出了重要貢獻(xiàn)。據(jù)統(tǒng)計，中國科大迄今已畢業(yè)的5萬人中，已有42人當(dāng)選中國科學(xué)院和中國工程院院士，是同期（自1963年以來）畢業(yè)生中當(dāng)選院士數(shù)最多的高校之一。其中，本科畢業(yè)生中平均每1000人就產(chǎn)生工名院士和700多名碩士、博士，比例位居全國高校之首。還有眾多的中青年才俊成為我國科技、企業(yè)、教育等領(lǐng)域的領(lǐng)軍人物和骨干。在歷年評選的“中國青年五四獎?wù)隆鲍@得者中，作為科技界、科技創(chuàng)新型企業(yè)界青年才俊代表，科大畢業(yè)生已連續(xù)多年榜上有名，獲獎總?cè)藬?shù)位居全國高校前列。

內(nèi)容概要

章節(jié)摘錄

插圖：I IntroductionNanocrystals are clusters of hundreds to hundred thousands of atoms withsizes from several to several hundred nanometers. Semiconductor nanocrystalsexhibit interesting size and shape dependent properties. 1-3 Due to its smallsize, a large fraction of atoms in nanocrystal are located on the surface. Manyphysical properties of nanocrystals, such as melting point and phase transitionpressure, are affected by this surface effect. In addition, the electronicstructure of nanocrystal is quite different from that of the bulk. Similar to thebulk, the electronic structure of semiconductor nanocrystals consists ofconduction band and valance band, separated by a band gap. However, thereare also discrete energy levels near the band edge, a feature otherwise onlyfound in molecules and atoms. Due to the quantum confinement effect, theband gap of semiconductor nanocrystals generally increases as its sizedecreases. Depending on the shape of the nanocrystal, the quantumconfinement can be 3D （quantum dot）, 2D （quantum rod）, or 1D （quantumwell） （Figure 1）.4Figure 1.
