About As3In2K2
As3In2K2 is a ternary inorganic compound composed of arsenic, indium, and potassium. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions. Its electronic character is defined as semiconducting, making it a subject of interest for fundamental solid-state research. The material is characterized by its specific stoichiometric balance, which influences its electronic band structure. Its stability suggests potential for synthesis and integration into experimental electronic devices where controlled semiconducting behavior is required.
Key Properties
Cross-validated computational properties for As3In2K2, aggregated across 3 databases.
