一、表面科学的研究内容表面科学是一门从六十年代末发展起来的多学科性的边缘科学.在超高真空条件下,研究金属及半导体表面上5～20??,即一个到几个原子层的厚度范围内,物质的成分、结构及电子、声子能态.它的研究,涉及超高真空物理,金属物理(金属的腐蚀及断裂),电化学催化及半导体物理等各个方面.它的具体内容包括以下三个方面. (1)表面成分的分析: 分析表面层内有无杂质,杂质的种类及杂质的含量.对于合金,分析研究表面层的成分与体内
A surface science research content Surface science is a multidisciplinary edge science developed from the late 1960s in ultra-high vacuum conditions, the study of metal and semiconductor surface 5 ~ 20 ??, that is, a few The thickness of the atomic layer, the composition of the material, structure and electronic, phonon energy state.Its research, including ultra-high vacuum physics, metal physics (metal corrosion and fracture), electrochemical and semiconductor physics and other aspects . Its specific contents include the following three aspects: (1) the analysis of surface composition: analysis of the surface layer with or without impurities, impurity types and impurity content.For the alloy, the analysis of the composition of the surface layer and in vivo
