Abstract

Time-domain terahertz (THz) spectroscopy was carried out on a c-axis oriented Bi₂Sr₂CaCu₂O_8+δ (BSCCO) thin film. We extracted various optical parameters at frequencies from 0.3 to 1.0 THz and temperatures from 5 to room temperature by numerically solving the observed complex transmittance without Kramers-Kronig analysis. As a result, the frequency dependence of surface resistance R_S showed different power laws of R_S∝f (f<0.5 THz) and R_S∝f^1/2 (0.5 THz <f) in the superconducting state. Below the characteristic frequency, f_C≃0.5 THz, rapid increase in the density of supercarrier, N_S, was obtained. These obtained results well explained the electromagnetic-wave radiation property which had been observed on the same BSCCO thin film.
