Abstract: There is growing interest in the quasi-one-dimensional chalcogenide Ta${}_{2}$NiSe${}_{5}$ due to proposals that its ground state is an excitonic insulator. Here, the authors report a comparative spectroscopic study of Ta${}_{2}$NiSe${}_{5}$ and Ta${}_{2}$NiS${}_{5}$ single crystals and… read more here.
