 abstract = {We report the first observation of the coexistence of a distinct midgap
state and a Mott state in undoped and their evolution in electron and
hole-doped ambipolar Y(0.38)La(0.62)dBa(0.82)La(0.18))(2)Cu3Oy films
using spectroscopic ellipsometry and x-ray absorption spectroscopies at
the O K and Cu L-3,L-2 edges. Supported by theoretical calculations, the
midgap state is shown to originate from antiferromagnetic correlation.
Surprisingly, while the magnetic state collapses and its correlation
strength weakens with dopings, the Mott state in contrast moves toward a
higher energy and its correlation strength increases. Our result
provides important clues to the mechanism of electronic correlation
strengths and superconductivity in cuprates.},
