Angle-Resolved photoemission spectroscopy on Tl2Ba2CuO6+δ
Abstract
Tl2201 is characterized by a simple and undistorted crystal structure, as well as less disorder than other high-Tc cuprate-based materials. On the very overdoped side of the phase diagram, a remarkable agreement has already been achieved between transport (i.e., AMRO and dHvA) and ARPES studies [1-3]. We here will present ARPES data on high-quality Tl2201 single crystals and compare them with transport results from the same material across the phase diagram, with emphasis on the evolution of Fermi surface volume, Fermi velocity, and many-body renormalization. We will also discuss the possibility of driving the doping on this material into the underdoped regime by in-situ potassium evaporation.[4pt] [1] N. E.
