Chemical compound
Titanium trisulfide (TiS3 ) is an inorganic chemical compound of titanium and sulfur . Its formula unit contains one Ti4+ cation , one S2− anion and one S2 2− .
TiS3 has a layered crystal structure, where the layers are weakly bonded to each other and can be exfoliated with an adhesive tape. The exfoliated layers have potential applications in ultrathin field-effect transistors .[ 2]
