An Evaluation of Optical Parameters of High-Temperature Superconductors

Sanju Kumari, Sobha Rani, S. Kumar and Lalit K. Mishra

Frequency dependent scattering rate and effective mass of electron were evaluated for two high Tc-superconductors using extended Drude model at different temperatures. Our theoretically evaluated result for scattering rate is large and effective mass is small in comparison with experimental data for the given temperatures. However, the trend for both the scattering rate and effective mass are in agreement with the experimental data and also with other theoretical workers.
