Abstract

We present a study of the of thermal transport in thin single crystals of iron-intercalated titanium disulphide, Fe $_{x}$ TiS $_2$ for $0\leq x \leq 0.20$ . We determine the distribution of intercalants using high-resolution crystallographic and magnetic measurements, confirming the insertion of Fe without long-range ordering. We find that iron intercalation perturbs the lattice very little, and suppresses the tendency of TiS $_2$ to self-intercalate with excess Ti. We observe trends in the thermal conductivity that are compatible with our ab initio calculations of thermal transport in perfectly stoichiometric TiS $_2$ .
