Studies of the Properties of the System TaS2−xSex
We have been interested for some time in the intercalation properties of many of the transition metal dichalcogenides with organic compounds. The 2Ha phase of TaS2, in particular, has been found to be readily intercalated by a wide range of organics,1 but it forms very poor crystals. On the other hand, 2Ha-TaSe2 forms nearly perfect crystals but is not readily intercalated. We have found that samples of the mixed anion system TaS2−x Se x are sufficiently well formed to carry out single-crystal measurements, yet they intercalate. For reviews of the structural and electrical properties of TaS2 and TaSe2, see Jellinek2 and Huisman and Jellinek,3 respectively.
