Aspects of normal-state resistivity of the cuprate superconductors Bi2Sr2CuO6+x,Tl2Ba2CuO6+x, and HgBa2CuO4+x

Abstract

Planar normal-state resistivity data from three families of hole-doped single-layer cuprate superconductors, i.e., Bi2201 (Bi2Sr2CuO6+x), Tl2201 (Tl2Ba2CuO6+x), and Hg1201 (HgBa2CuO4+x), are calculated using the extremely correlated Fermi liquid theory (ECFL). This theory was recently employed by us to compute the resistivity of three families of single-layer cuprate superconductors, i.e., La2−xSrxCuO4 (LSCO), Bi2Sr2−xLaxCuO6+δ (BSLCO), and Nd2−xCexCuO4 (NCCO), followed by a detailed comparison. Adding the three systems studied here accounts for all the remaining single-layer compounds, where data are available for a range of densities and temperatures, thereby providing a comprehensive study of one class of important cuprate superconductors. The added study of the material Bi2201 is of particular interest since it is the system where the almost linear in temperature resistivity was first reported in 1990. Only recently, in 2022, has a systematic doping analysis become available. The Tl2201 system has two distinct sets of band parameters that fit the same Fermi surface, providing new challenges and insights into the ECFL theory.
