AsI3
semiconductor· AsI3
Arsenic triiodide (AsI₃) is a layered semiconductor compound belonging to the trihalide family, characterized by weak van der Waals interactions between atomic layers. This material is primarily of research interest for next-generation optoelectronic and photovoltaic devices, where its layered crystal structure and tunable bandgap make it a candidate for two-dimensional device engineering and perovskite-alternative absorber layers. AsI₃ remains largely experimental; its appeal lies in potential alternatives to conventional semiconductors in emerging applications where layer-dependent electronic properties and mechanical flexibility are advantageous.
