表面纳米结构的自组装生长

Self-organized growth of surface nanostructures

无论是对低维基本物理以及其中新奇量子现象的探索与认识,还是微电子工业水平的持续发展,都迫切地需要掌握一种能够精确、可靠地操控表面纳米结构的方法.自组织生长,即粒子聚集时由于介观尺度力场或受限运动作用而导致的自发有序现象,在原子尺度上可以实现对纳米结构的精确控制,而在介观尺度上又可以调节这些微观结构单元的组织构型.文章结合作者近年来在表面纳米结构生长与物理性质研究方面所做过的工作,从自组织生长的原理出发,介绍了对金属纳米线、有序分子薄膜以及合金量子点阵列生长进行人工操控的方法.

To control the growth of surface nanostructures precisely and dependably is crucial for the exploration of fundamental physics and novel quantum phenomena in low - dimensional systems, as well as for the continuable development of the microelectronic industry. Self-organized growth, an autonomous order phenomenon mediated by mesoscale force fields or kinetic limitations in growth the atomic scale and their organization at mesoscale levels. processes, enables the control of nanostructures on Starting from our recent study of the growth and properties of surface nanostructures we discuss both the basic physics of self-organized growth and the controllability of metal nanowires, ordered molecule films, and arrays of metal alloy nanodots.
