Abstract
The doping density (delta) dependence of the in-plane resistivity rho (ab) and Hall effect (the Hall coefficient R-H and the Hall angle cot theta (H)) of' high-T-c cuprate superconductors is analyzed by using recent results o f doping-dependent quasiparticle dispersion worked out by Yin and co-worker s [Phys. Rev. Lett. 81, 2534 (1998)]. The cold-spot model for the quasipart icle scattering proposed by Ioffe and Millis [Phys. Rev. B 58, 11631 (1998) ] is adopted in the relaxation time approximation of standard transport the ory. We find qualitatively rho (ab)(T) is linear in the high doping region and is semiconducting in the: deep underdoped case. We also obtain R-H and T* (the temperature at which transport properties start to show anomalous b ehaviors) versus S relations in agreement with experimental data.
