Description
We have performed a detailed temperature-dependent angle-integrated photoemission study of lightly-doped to heavily-overdoped La2-xSrxCuO4 and oxygen-doped La2CuO4.10. We found that, while the magnitude of the (small) pseudogap Δ* increased with decreasing hole concentration, that of the superconducting gap Δsc did not increase
