· SbI3

Antimony triiodide (SbI₃) is a layered semiconductor compound belonging to the pnicogen trihalide family, characterized by weak van der Waals bonding between atomic layers that enables mechanical exfoliation. While primarily in the research phase rather than established industrial production, SbI₃ is being investigated for optoelectronic and photovoltaic applications due to its semiconducting properties and tunable band structure, positioning it as a candidate material for next-generation thin-film devices, particularly where layered heterostructure architectures are advantageous.
