Abstract

We have found that the substitutional replacement of Ti for Ta in Ta $S_{2}$ stabilizes the octahedral $1 T$ phase for $x$ between 0.1 and 0.9. A comparison of the resistivity, magnetic susceptibility, and thermoelectric power shows that at room temperature the properties vary systematically from diamagnetic, semiconducting behavior for $1 T - T a S_{2}$ to paramagnetic, metallic behavior for Ti $S_{2}$ . This interpretation of the data contradicts all previous models which treat Ti $S_{2}$ as a degenerate semiconductor.
