Abstract

- Literature data for the in-plane electrical resistivity ρ of single-crystal La2-xSrxCuO4 with 0.07 ≤x≤0.34 have been corrected to constant crystal volume V using literature data for the pVT properties and for the resistivity vs pressure p. The original data at constant p show the usual anomalies observed for ceramic high-transition-temperature superconductors, such as linearity of ρ to extremely high T at optimum doping and an upwards curvature (ρ∝T1.5) for overdoped material. After correction, the data for ρ at constant volume are linear in T for overdoped material only. We show that phonons cannot be ruled out as the major carrier scattering agent.
