Ta2NiS5

Ta2NiS5 crystals have been synthesized at our facilities using flux vapor transport method which is known to be one of the most pristine and high-quality growth technique. Ta2NiS5 crystals are layered crystals with rather unique structural and crystal characteristics (see images). While their materials properties are largely unknown they are excitonic insulators much similar to Ta2NiSe5 and Ta2NiTe5.
