Abstract :
A direct preparation of polycrystalline layers of β-ET2I3 by reaction of ET and I2 in swollen polymer film at elevated temperature is shown. The films obtained under optimum conditions show metallic d.c. conductivity down to liquid helium temperature. XRD and Raman spectra confirm the formation of ET2I3 β-phase. In the films obtained at non-optimum conditions (short treatment time and/or lower temperature) a mixture of α and β-phase is obtained. Such films become semiconducting a low temperatures.
