Laser-ARPES Study on Electron Scattering in Overdoped Bi2201 Superconductor
ORAL
Abstract
We will present our high resolution angle-resolved photoemission (ARPES) measurements on heavily overdoped Bi$_{\mathrm{2}}$Sr$_{\mathrm{2}}$CuO$_{\mathrm{6}}$ superconductors. With substitution of lead (Pb) and high oxygen pressure annealing, overdoped and heavily overdoped Pb-doped Bi$_{\mathrm{2}}$Sr$_{\mathrm{2}}$CuO$_{\mathrm{6+}}$ (Pb-Bi2201) single crystals have been prepared. Laser-based ARPES measurements with high energy and momentum resolutions have been carried out to study the electron scattering rate as a function of momentum and temperature for Pb-Bi2201 with different doping levels. The implication of these results on understanding the anomalous normal state properties of the high temperature cuprate superconductors will be discussed.
