Description

The high brightness light source of synchrotron radiation provides a variety of experimental techniques for probing the material. Some techniques such as x-ray photoelectron spectroscopy (XPS) and angle-resolved photoemission spectroscopy (ARPES) are widely used for the investigation of the electronic structure of occupied electronic states of solid. While the details of the unoccupied states can be obtained by the x-ray absorption spectroscopy (XAS). Furthermore, near ambient pressure x-ray photoelectron spectroscopy (NAP-XPS) is used for a variety of material such as catalyst due to the much technological application. In my talk, these spectroscopy techniques with some examples are explained.
