一、引言纳米科技是在(0.1~100)nm范围内,研究电子、原子和分子内的运动规律、特性和应用的一门科学技术。当粒子尺寸减小到纳米尺度,到某个临界值时,将会出现量子尺寸效应,导致纳米微粒的光、电、磁、热、声及超导电性与宏观特性显著不同,呈现出新的小尺寸效应,纳米技术即是利用这些特性制造出具有特定功能的物质或设备。纳米技术是一门交叉性很强的综合学科,研究内容涉及现代科技的广阔领域。主要包括纳米体系物理
I. INTRODUCTION Nanotechnology is a science and technology that studies the laws of motion, characteristics and applications of electrons, atoms and molecules in the (0.1 ~ 100) nm range. When the particle size is reduced to the nanometer scale, the quantum size effect will occur at a certain critical value, resulting in the significant difference in the optical, electrical, magnetic, thermal, acoustic, superconductivity and macroscopic properties of the nanoparticle, presenting a new Small size effect, nanotechnology is the use of these features to create a specific function of the substance or equipment. Nanotechnology is a comprehensive and interdisciplinary subject that covers a vast area of modern science and technology. Mainly include nanosystem physics
