Abstract
The doping density (δ) dependence of the in-plane resistivity ρab and Hall effect (the Hall coefficient RH and the Hall angle cotθH) of high-Tc cuprate superconductors is analyzed by using recent results of doping-dependent quasiparticle dispersion worked out by Yin and co-workers [Phys. Rev. Lett. 81, 2534 (1998)]. The cold-spot model for the quasiparticle scattering proposed by Ioffe and Millis [Phys. Rev. B 58, 11 631 (1998)] is adopted in the relaxation time approximation of standard transport theory. We find qualitatively ρab(T) is linear in the high doping region and is semiconducting in the deep underdoped case. We also obtain RH and T* (the temperature at which transport properties start to show anomalous behaviors) versus δ relations in agreement with experimental data.
