✦ Synopsis

The thin film of bis(ethylenedithio)-tetrathiafulvalene (BEDT-TTF or ET) radical salt with Dawson polyoxometalate [P 2 W 18 O 62 ] 6-was prepared on gold substrate by using electrochemical process. The film was characterized by Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), electron spin resonance spectroscopy (ESR) and cyclic voltammetry (CV).

Scanning electron microscope (SEM) micrograph of the film exhibits a smooth and uniform surface layer containing micronic grains. The thickness of the film estimated by SEM is ca. 22 m. The film exhibits semiconducting behavior with a room-temperature conductivity 6.5 × 10 -3 S cm -1 .
