Research Abstract

In this research, we focused on terahertz wave, which has not been used for a long time because of the lack of the proper way to generate and detect, and we used it for the spectroscopy measurement. We have developed a terahertz time-domain spectroscopy (THz-TDS) system and measured reflectivity spectra of high-Tc superconductor La_<2-x>Sr_xCuO_4 (x=0.10, 0.12, 0.13, 0.15). We found double-Josephson-plasma like behavior in the reflectivity and the optical conductivity only for x=0.13 which has spin and charge stripe order.
