We report the fabrication of field-effect transistors on single crystals of the highly anisotropic organic semiconductor tetramethyltetraselenafulvalene. We find maximum mobilities of at room temperature. We observe an exponential decrease of mobility with decreasing temperature with an activation energy independent of sample quality or fabrication method.

The bandgap of pure TMTSF has never been measured. However, the crystals are clear and violet in color, indicating that the bandgap exceeds 2.5 eV. In addition, there are no reports of the Debye temperature.
