摘要
The infrared reflectivity of the organic conductor alpha-(BEDT-TTF)(2)KHg(SCN)(4) has been measured as a function of polarization and temperature. The optical conductivity spectra obtained by the Kramers-Kronig analysis show different electronic contributions due to interband and intraband excitations. The vibrational features are assigned and compared to the superconducting analogue alpha-(BEDT-TTF)(2)(NH4)Hg(SCN)(4), (C) 2002 Elsevier Science B.V. All rights reserved.
