Abstract
athiafulvalene-7,7,8,8-tetracyano-p-quinodimethane (TTF-TCNQ) thin fil ms were prepared on common glass by chemical vapour deposition (CVD) a t low pressure and using tetrathiafulvalene and tetracyanoquinodimetha ne as precursors. The layers exhibit a preferential orientation in the crystallization along the [001] direction and have a room-temperature conductivity of 6-24 Omega(-1) cm(-1). The evaluation of the stoichio metry was performed by UV-Vis spectroscopy. Crystallite orientation wa s determined by electron paramagnetic resonance (EPR) spectroscopy. Th e morphology and structure of the layers were also studied.
