扫描探针显微学在材料表面纳米级结构研究中的新进展

ADVANCES IN THE STUDY OF NANOSCALE SURFACE STRUCTURES BY SCANNING PROBE MICROSCOPY

应用扫描探针显微技术（ＳＰＭ）［包括扫描隧道显微镜（ＳＴＭ）、原子力显微镜（ＡＦＭ）、磁力显微镜（ＭＦＭ）等］，比较系统地研究了一些无机、有机和生物材料的表面精细结构；在极高分辨率的水平上，解释了如Ｃ６０Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔ膜、有机磁性薄膜的结构与样品制备、形成条件的关系；研究并揭示了碱金属与半导体表面吸附相互作用，红细胞表面精细结构等；拓宽了扫描探针显微技术的应用范围，在实验方法和研究成果上具有明显的创新性．

The fine strucutres of several kinds of organic,inorganic and biological materials have been investigated using scanning tunneling microscopy,atomic force microscopy and magnetic force microscopy.The relationship between the structures and the sample preparation methods of films such as C 60 Langmuir-Blodgett films and organic magnetic films have been explained.The adsorption of alkali metals on semiconductor surfaces and the fine structure of red blood cells have been studied in detail.The experimental methods are novel and the results new,further expanding the field of application of scanning probe microscopy.
