| Abstract: | A detailed phenomenological model is developed for the normal state transport properties of optimal and overdoped high-Tc 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 Tl2Ba2CuO
6 + δ
and Bi2Sr2CaCu2O
8 + δ
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 Bi2Sr2CaCu2O
8 + δ
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.
