微尺度观测仪(AFM)原理及应用 摘要 1982年,{dy}台扫描隧道显微镜(STM)的问世,使得人类首次能够实时地观察单个原子在物质表面的排列状态。但由于其只能用来直接观察和研究导体和半导体样品的表面,存在很大的局限性,原子力显微镜(AFM)应运而生。经过十几年的技术改进,凭借其纳米量级的精度和不受样品表面导电性限制的优势奠定了它作为一种独立的表面分析仪器的地位,其应用随着纳米科技热的兴起而日益引起人们的重视,仪器本身的稳定性、图像质量、操作的简便性以及应用领域的拓展和产业化也越来越受到关注。 本次论文工作首先回顾了显微镜(Microscopy)的发展历程,对原子力显微镜的工作原理进行了理论上的探讨,并针对重庆大学研制的AFM.IPC-208B型机进行了整机系统的深入了解,对在研制和应用过程中碰到的问题,提出了相应的改进方案,并进行了初步的实验研究,积累了应用经验。, 关键词:显微镜,微尺度,原子力显微镜,探针, Inheritance Algorithmic Parameter Analysis ABSTRACT The appearing of the first STM in 1982 makes human being be able to observe thearran gement of a single atom on the material's surface ,however ,it has a lot of limitations that it is only used to observe and research on the surface of conductor and semiconductor,so the AFM had been come out. With the rapid progress in technology during the past more than ten years, AFM establishes its status as a kind of surface analyzed apparatus depending on nanometer-level resolution and unlimited conduction of samples ,and its application also attracts more and more attention with the improving of nano-technique. Because of its stabilization, convenient, the excellent quality of the picture, people concern more about its application area and industrialization. The paper firstly introduces the development of Micoscopy,and the foundational principles of AFM, and then, make a good expatiate of the whole system of the AFM.IPC-208B developed by Chongqing University. It has brought some suggestions to the problems in development and experiment. Becase the probe plays an important role in experiment.
