TiS3

TiS₃ is a layered transition metal trichalcogenide semiconductor composed of titanium and sulfur in a 1:3 stoichiometry. This material is primarily of research interest rather than established industrial use, with potential applications in two-dimensional electronics and optoelectronics due to its layer-dependent properties and ability to be exfoliated into thin sheets. Engineers investigating TiS₃ are typically exploring it as an alternative to graphene and transition metal dichalcogenides (TMDs) for next-generation semiconductor devices where the material's unique electronic structure and mechanical compliance could enable flexible electronics, photovoltaic absorbers, or field-effect transistors.
