扫描隧道显微镜在相变研究中的应用

STUDY OF PHASE TRANSITIONS BYSCANNING TUNNELLING MICROSCOPY

阐述了扫描隧道显微镜（ＳＴＭ）的工作原理，及其特点，总结了ＳＴＭ在金属、半导体材料的原子结构观察及表面相变等方面的主要研究成果它包括纯金属及半导体原子结构、表面相变、表面吸附（表面反应）及表面物理沉积过程的动态研究；

The working mechanism of Scanning Tunnelling Microscope(STM),which is a novel surfaceanalysis apparatus with very high resolution,is briefly introduced. Some of those important experimental results as to the STM investigation of the atomic structure and surface transition of metals and semiconductorsare collected in this paper, such as in situ study on atoms, surface transition, surface absorption (surface reaction), and physical depostition, etc.. The experimental techniques and new results of STM of phase structureand phase transition are given in full length here.
