TiSe2 is a band insulator created by lattice fluctuations, not an excitonic insulator
Abstract TiSe2 is a narrow-gap insulator with a rich array of unique properties. In addition to being a superconductor under certain modifications, it is commonly thought to be a rare realisation of an excitonic insulator. Below 200 K, TiSe2 undergoes a transition from a high-symmetry ( $$P\bar{3}m1...
