Abstract

A study of the normal state optical response of epitaxial thin films of electron doped superconductor Nd_1.85Ce_0.15CuO_4-y is reported. The normal state optical response of these films were not proportional to the temperature derivative of the resistance of the films as expected by a bolometric model and as seen in p-type superconductors such as YBa₂Cu₃O_7-δ. The normal state optical response of the films with different transition temperatures were also remarkably different from each other. The observation of anomalous optical response is attributed to the possible presence of photoconductivity in Nd_1.85Ce_0.15CuO_4-y.
