國際材料科學(xué)領(lǐng)域頂尖綜述期刊Progress in Materials Science(2012年影響因子23.194)最近一期刊登了一篇關(guān)于納米材料生長機(jī)制的文章,即X. L. Li, C. X. Wang, and G. W. Yang*, Thermodynamic theory of growth of nanostructures, Progress in Materials Science, 64, 121 (2014)。該文章是Open Access,可以任意下載,網(wǎng)址 http://www.sciencedirect.com/sci ... i/S0079642514000255 ,附件里也有。希望對研究納米材料的同行有幫助。摘要如下: Self-assembled nanostructures, such as quantum dots (QDs), quantum rings (QRs) and nanowires (NWs), have been extensively studied because of their physical properties and promising device applications. To improve their physical properties and device applications, the fabrication of nanostructures with a uniform size, proper shape and regular position is desired in nanotechnology. Therefore, investigations of the growth process of nanostructures are highly important to control the self-assembly and synthesis processes of nanostructures flexibly. Thermodynamic theory as a universal approach to investigate material growth has been widely used to study the growth of nanostructures. This review covers the thermodynamic theoretical treatments of the growth of nanostructures, including QDs by epitaxy, QRs by droplet epitaxy, and NWs by the vapor–liquid–solid (VLS) mechanism. First, we introduce the thermodynamic models of the growth mechanisms of QDs by self-assembled epitaxy. The formation, stability, shape and position of QDs are discussed. Second, we introduce the nucleation thermodynamics and the growth kinetics of QRs by droplet epitaxy, and we present a simulation method employing the shape evolution of QRs based on a kinetic model. Third, several theoretical tools are introduced to address the nucleation and growth of NW by the VLS process. Finally, we introduce a thermodynamic treatment including the thermal fluctuations within the context of a statistical mechanical and quantum mechanical model for the temperature-dependent growth of nanostructures.
