Abstract

We have measured the thermal conductivity of TI2Mo6Se6, a quasi-one dimensional conductor which belongs to the family of M2Mo6X6 linear chain compounds. Using these results and our measurements of the Seebeck coefficient and the electrical conductivity we estimate the dimensionless figure of merit to be of the order of 0.08. This result suggest that this compound and other related compounds are good potential TE.
