Abstract
We report on infrared studies of the c-axis electrodynamics of Tl2Ba2CuO6+δ crystals. A sum-rule analysis reveals spectral weight shifts that can be interpreted as a kinetic energy change at the superconducting transition. In optimally doped crystals, showing an incoherent normal-state response, the kinetic energy is lowered at T<Tc, but no significant change is found in the overdoped samples, which have more coherent conductivity at T>Tc.
