Ag3AsSe3

Ag3AsSe3 is a ternary semiconductor compound combining silver, arsenic, and selenium—a material from the family of chalcogenide semiconductors with mixed-valent metal cations. This is a research-phase compound rather than a commercial material; it represents exploration in the arsenic-based chalcogenide space, a field pursued for potential optoelectronic and photonic applications where narrow bandgaps and specific refractive properties are valuable. Interest in such compounds stems from their potential use in infrared sensing, nonlinear optical devices, and photovoltaic systems where materials combining high atomic number elements with controllable electronic structure offer advantages over more conventional semiconductors.
