HAXPES is recognized a powerful tool for investigating the chemical states and electronic structures of various materials with third generation high-brilliance synchrotron radiation sources. The most advantageous feature of HAXPES is enabling us to measure intrinsically bulk sensitive electronic structures and buried interface profiles. The large depth of the information provided by HAXPES has expand various applications both in basic and applied research fields. Furthermore, We have developed the ambient pressure cell which could keep the environments for wet sample including H₂O adsorption in a high vacuum successfully and realized to observe the electronic states of the solution sample using hard X-ray photoemission spectroscopy (HAXPES) at BL47XU in SPring-8.
