摘要:

硅納米晶體作為最重要的元素半導體�补璧囊环N納米形式，由于具有獨特的光電特性和友好的環(huán)境相容性引起了研究者們的廣泛關(guān)注。近年來，人們圍繞著量子限域效應(yīng)、表面效應(yīng)和摻雜效應(yīng)三個最重要的因素對硅納米晶體的性質(zhì)開展了研究，并通過三者對硅納米晶體的電學和光學性能進行調(diào)控，使其滿足面向印刷電子、硅基集成和生物兼容的高性能光電器件的應(yīng)用。目前，基于硅納米晶體的太陽能電池、發(fā)光二極管和光電探測器等重要光電器件已經(jīng)被研制出來。綜述了近年來國內(nèi)外研究者們在硅納米晶體的制備、性質(zhì)研究及其在光電器件中的應(yīng)用所取得的研究進展，并展望了硅納米晶體在材料性能調(diào)控方面的發(fā)展前景。

Abstract:

As one of the nanostructures of the most important elemental semiconductor�瞫ilicon, silicon nanocrystals have attracted great research interests given their remarkable optoelectronic properties and environmental friendliness. In the past decades, tremendous work has been carried out to understand the quantum confinement effect, surface effect and doping effect of silicon nanocrystals and to modify the electric and optical properties of silicon nanocrystals for the purpose of applications in printed electronics, silicon�瞓ased optoelectronics and biocompatible high�瞤erformance optoelectronics. Up to now, typical optoelectronic devices based on silicon nanocrystals including solar cells, light�瞖mitting diodes and photodetectors have been successfully fabricated. The paper summarizes the recent progress obtained on the investigations of the synthesis, properties and optoelectronic device applications of silicon nanocrystals. In addition, we outlook the perspective of silicon nanocrystals with desirable properties for high�瞤erformance device applications.
