清洁及单层吸附的Mo(001)表面声子色散研究

STUDY ON PHONON DISPERSION OF CLEAN AND MONOLAYER ADSORBED Mo(001) SURFACE

用最近邻及次邻中心相互作用势讨论了清洁的Mo(001)表面声子。作为初步近似,用质量亏损模型讨论了不同吸附原子质量对表面声子的影响。

Using the nearest and next nearest neighbor central interactions, phonons of clean Mo(001) surface are studied. As a primary approximation, the effects of different adsorbed atom masses on surface phonons are discussed by a simple mass defect model.
