一、固体表面和表面分析 固体物质都有表面.在这里,表面通常是指固体最外层的1—10个原子层,其厚度大约是几个至几十个埃.有时表面还包括被吸收进表面晶格和吸附在表面上的那些外来原子.表面层中的原子数在整个固体的原子总数中所占的比例是很小的.但表面层的组分和性质往往和 Solid Surface and Surface Analysis Solid surfaces have a surface, where the surface generally refers to 1-10 atomic layers of the outermost layer of solid with a thickness of about a few to tens of angstroms.Of course, the surfaces also include those that are absorbed Into the surface of the lattice and adsorbed on the surface of those foreign atoms in the surface layer of the total number of atoms in the solid atoms in the total number of atoms is very small.However, the composition and nature of the surface layer often
