Hard X-ray Photoelectron Spectroscopy: Applications To Energy Materials

Wednesday, December 14, 2016, 6:00 pm, Room Lehua

We have recently commissioned a new Hard X-ray Photoelectron Spectroscopy (HAXPES) system on the undulator beamline at the Materials Research Collaborative Access Team (MRCAT). This system was built to study materials of interest in energy storage and generation. There are a number of problems where knowledge of the electronic structure of materials is of great interest. Specifical, how is the electronic structure modified due to chemistry, irradiation, structural change, disorder, etc. The MRCAT HAXPES system is designed to operate with photon energies between 6 keV and 12 keV. This will allow us to study the electronic structure of these materials as a function of depth. Our initial measurements have been on thin films utilized in lithium ion batteries and in claddings used in nuclear reactor fuels. We will discuss these results and describe other experiments that can be conducted at the new HAXPES facility.
