The study of electronic nematicity in an overdoped (Bi, Pb)₂Sr₂CuO_6+δ superconductor using scanning tunneling spectroscopy.

ABSTRACT: The pseudogap (PG) state and its related intra-unit-cell symmetry breaking remain the focus in the research of cuprate superconductors. Although the nematicity has been studied in Bi₂Sr₂CaCu₂O_8+δ, especially underdoped samples, its behavior in other cuprates and different doping regions is still unclear. Here we apply a scanning tunneling microscope to explore an overdoped (Bi, Pb)₂Sr₂CuO_6+δ with a large Fermi surface (FS). The establishment of a nematic order and its real-space distribution is visualized as the energy scale approaches the PG.
