表面物理是近二十年来迅速发展起来的一门新兴的前沿学科.它研究物体表面的物理现象,包括成分和原子结构的变化,电子状态和原子、分子和表面的相互作用,以及这些物理现象对物体各种性质的影响.这些研究给改进电子器件的性能,控制表面化学反应,以及发展各种新材料提供了可靠的根 Surface physics is a newly developed frontier subject that has developed rapidly in the recent two decades. It studies the physical phenomena on the surface of an object, including the change of composition and atomic structure, the electronic state and the interaction of atoms, molecules and surfaces, and the physical phenomena Impact on various properties of the object These studies provide a reliable root for improving the performance of electronic devices, controlling surface chemical reactions, and developing a variety of new materials
