The normal state scattering rate in high-Tc cuprates

A detailed phenomenological model is developed for the normal state transport properties of optimal and overdoped high-T-c cuprates. In particular, an explicit- form of scattering rate is identified that may account, qualitatively and quantitatively, for the normal state (magneto)-transport properties of Tl(2)Ba(2)CuO(6+)delta and Bi2Sr2CaCu2O8+delta across the overdoped side of the phase diagram. The proscribed form of the scattering rate is consistent also with features seen in the photoemission spectroscopy of Bi2Sr2CaCu2O8+delta and offers a new and intuitive way to understand the evolution of the temperature dependence of the inverse Hall angle in Bi-based cuprates with carrier concentration.
