Abstract: | The polarized reflectance spectrum of a novel organic conductor, (BEDT-TTF)2ClO4(C2H3Cl3)0.5 was measured at room temperature over the spectral region from 340 cm-1 to 25000 cm-1. The reflectance spectrum provided an evidence for the anisotropic two-dimensional character of this material. The optical conductivity spectrum exhibits the existence of an optical band gap of about 0.2 eV, suggesting that this material is a semimetal rather than a metal. |
