· Ta1 In1 Se2

Ta₁In₁Se₂ is a ternary layered semiconductor compound composed of tantalum, indium, and selenium. This material belongs to the family of two-dimensional (2D) transition metal chalcogenides and is primarily investigated in research contexts for its potential in electronic and optoelectronic applications. The layered structure and tunable band gap make it a candidate for next-generation nanoelectronics, photovoltaics, and sensing devices where van der Waals heterostructures can be engineered.
