引言近年来,光电子能谱技术获得迅速发展,其应用的深度和广度都在不断扩大。这门技术的基础是精确测定物质中束缚电子的结合能量。能量关系是 E_b=hn-E_k-φ_(sp) 式中,E_b是电子结合能,hv是物质吸收的入射光子能量,E_k是被测样品所发射光电子的能量,φ_(sp)是谱仪材料的功函数。因为φ_(sp)同样品无关,只要它的值不随时间变化,则φ_(sp)的校 Introduction In recent years, the rapid development of photoelectron spectroscopy technology, the depth and breadth of its application are constantly expanding. The basis of this technique is the precise determination of the binding energy of the bound electrons in the material. Energy relationship is E_b = hn-E_k-φ_ (sp) where E_b is the electron binding energy, hv is the incident photon energy absorbed by the substance, E_k is the energy of the photoelectron emitted by the sample under test, and φ_ (sp) The work function. Because φ_ (sp) has nothing to do with the same sample, as long as its value does not change over time, then φ_ (sp)
