The Effect of V and Nb Impurities on the Electronic Properties of TiSe2
TiSe2 is a semimetallic compound undergoing a second order structural phase transition at about 200 K. At room temperature, the electrical conductivity σ = 103 −1cm−1 is dominated by positive charge carriers. In relation with the phase transition a change of sign of the Hall coefficient has been measured and the crystal becomes n type at low temperature with an absolute value of the Hall constant depending on the stoichiometry.
