This TlInS2 vdW crystal has been synthesized by floating zone technique. TlInS2 semiconductors belong to the thallium chalcogenide family, members of which have layered and chain-like structures. The atomic stacks in the TlGaSe2, TlGaS2 and TlInS2 layered crystals are arranged in the form of two twisted anion layers with weakly bonded Tl(+1) cations located in a triangular cavity between them. As a result, these crystals exhibit a layered structure with weak vdW coupling between adjacent layers. Alfa Chemistry Materials product group: 2D Alloys Manufacturer data sheet |
