Our current research involves the study of complex material systems. Most notable among these are the strongly correlated electron systems, such as the high-temperature superconductors and the Mott insulators. We study these systems by probing their interactions with electromagnetic radiation, ranging from x-rays, to the ultraviolet, and into the microwave regime. Our research also involves exploration of materials inspired by energy applications, such as novel diamondoids for lighting, field emission, and photon-enhanced thermionic emission (PETE).
Our primary experimental tool is angle-resolved photoemission spectroscopy (ARPES), but we also perform x-ray absorption and emission measurements. Recently, we have also started experiments using resonant x-ray scattering and near-field microwave microscopy techniques. We help maintain two experimental endstations (Beamline 5-4 & Beamline 5-2) at the Stanford Synchrotron Radiation Lightsource (SSRL), one endstation (Beamline 10.0.1) at the Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory (LBNL), near the University of California, Berkeley.
