The electrical resistivity parallel to the layers of Se-doped 1T-TaS2 has been measured over the range 1.3 < T < 240 K. Results support the existence of disorder-induced carrier localization in this material. Anisotropy studies in pure samples show that θc/θa ~ 500, where θc and θa are the resistivities normal and parallel to the layers, respectively, suggesting that the conduction is 2-dimensional.
