Program Description
X-ray elastic scattering is one of the most important techniques in physics, chemistry, and material research, which reveals information about crystal structure and periodicity of materials. Resonant x-ray scattering, in which incident photon energy coincides with absorption edge, offers a unique element and chemical specific probe to study spatial periodicity of charge, orbital, spin, and also structural degree of freedom of the materials. When we tune the photon energy to soft x-ray range which covers carbon and oxygen K-edges, 3d transition metal L-edge, and rare-earth M-edge, we can obtain valuable information from the large enhancement of signal, direct observation of partially occupied electronic states, and sensitivity to bonding structure especially in device and energy materials.
In this talk, I’ll introduce resonant soft x-ray scattering (RSXS) technique firstly and an introduction of recently built RSXS endstation as a new capability of SSRL will be followed. Finally, several recent results and utilizations of RSXS on quantum materials will be presented.
