Abstract

We have unambiguously observed the c-axis Josephson plasma resonance (JPR) in high-critical-temperature Tc cuprate Tl2Ba2CaCu2O8 superconducting thin films, employing terahertz time-domain spectroscopy in transmission as a function of temperature in zero magnetic field. These are believed to be the first measurements of the JPR temperature dependence of a high-Tc material in transmission. With increasing temperature, the JPR shifts from 705  GHz at 10  K to 170 GHz at 98  K, corresponding to an increase in c-axis penetration depth from 22.4±0.6 μm to 94±9 μm. The linewidth of the JPR peak increases with temperature, which indicates an increase in the quasi-particle scattering rate. We have probed the onset of the c-axis phase coherence to 0.95 Tc. The JPR vanishes above Tc as expected.
