VUV Laser-Based ARPES on Electronic Structure of High Temperature Superconductors
ORAL
Abstract
The last decade has witnessed a dramatic improvement of the angle-resolved photoemission spectroscopy (ARPES) technique in terms of energy and momentum resolution. This in turn has resulted in a number of new findings on the electronic structure of high-Tc cuprate superconductors, particularly the identification of many-body effects. In this talk, we will present results on the electronic structure of high-Tc superconductors measured from our new ARPES system based on VUV laser, realized by frequency doubling from a non-linear optical crystal KBBF. The laser-based ARPES system has ultra-high energy resolution, high photon flux, and a potential to enhance bulk sensitivity.
