Abstract

Planar normal state resistivity data from two families of hole doped single layer cuprate superconductors Bi2201 (Bi₂Sr₂CuO_6+x) and Tl2201 (Tl₂Ba₂CuO_6+x) are calculated using the extremely correlated Fermi liquid theory (ECFL). This theory was recently employed for understanding the three families of single layer cuprate superconductors LSCO, BSLCO and NCCO. Adding these two systems accounts for essentially all single layer compounds where data is available for a range of densities and temperatures. The added case of Bi2201 is of particular interest since it was the original system where the almost linear in temperature resistivity was reported in 1990, and has been followed up by a systematic doping analysis only recently in 2022. The Tl2201 system has two distinct set of band parameters that fit the same Fermi surface, providing new challenges and insights into the ECFL theory.
