Abstract

Photo-induced carrier relaxation dynamics have been investigated for the organic superconductor κ-(BEDT-TTF)2Cu(NCS)2 with different probe polarization under 1.3 kbar at low temperatures. We successfully observed the isotropic and anisotropic responses for the probe polarization, which were found to appear at 56 K. By comparing the responses with and without applying pressure, we found that those were slightly changed, indicating that the application of pressure has effect on the carrier relaxation dynamics.
