· Na2 In2

Na₂In₂ is an intermetallic compound composed of sodium and indium, belonging to the class of alkali metal–group 13 semiconductor materials. This is a research-stage compound primarily studied for its electronic and photonic properties rather than established in widespread industrial production. The material family shows potential in optoelectronics and next-generation semiconductor applications where lightweight, earth-abundant alternatives to conventional semiconductors are sought, though practical device implementations remain largely experimental.
