Abstract

Ca doped YBaCuO thin films were investigated using frequency and time domain THz spectroscopy. A non-monotonic behavior was observed in with a maximum at about 1.8 meV and 1.2 meV depending on Ca concentration. Two batches of thin films 500-600Å thick where used; one of 5% and the other of 10% Ca concentration. The films show a clear c-axis orientation and 77K for the 5% Ca and 10% Ca respectively. Both thin film batches show a decrease in plasma frequency as temperature increases and superconducting transition is approached. The quasiparticles scattering rate decreases in the normal state and drops when T_c is approached. The imaginary part of the conductivity was found to be proportional to 1/ω, known from the delta-function response.
