Doping-dependence of CDW Order in Bi2201, Measured by Phase-Sensitive STM

ORAL

Abstract

The cuprate phase diagram shows a charge density wave (CDW) dome within the pseudogap regime and intersecting the superconducting dome. However, there are important variations among members of the cuprate high-Tc family that can yield deep insight into how the phases interact. Here, we use scanning tunneling microscopy to investigate the doping dependence of the CDW order in (Bi,Pb)$_2$(Sr,La)$_2$CuO$_{6+\delta}$ (Bi2201). Sublattice-resolved phase sensitivity allows us to disentangle electronic components with different intra-unit cell symmetry. The energy and doping dependent evolutions show a connection with the superconducting and pseudogap phases.
