| 英文摘要 | oxygen adsorption and desorption on a pd(100) surface with a mesoscopic defect were studied by photoemission electron microscopy (peem). the defect surface, with an area of approximately 200 x 60 mu m(2), behaved differently from the perfect pd(100) surface towards the adsorption of oxygen. when saturated, both surface oxygen and subsurface oxygen coexisted on the defect surface, whereas only surface oxygen was present on the pd(100) surface. upon heating, subsurface oxygen diffused back to the surface and desorbed with surface oxygen at the same time. the difference in oxygen adsorption ability between the defect surface and the perfect pd(100) surface can be attributed to different structures of these two surfaces.
