CoAs3

CoAs₃ is a cobalt arsenide semiconductor compound belonging to the metal pnictide family, typically studied as a narrow-bandgap or semimetallic material with potential for high-mobility electronics. While primarily a research material rather than a production commodity, cobalt arsenides are investigated for thermoelectric applications, high-frequency transistors, and optoelectronic devices where their electronic band structure and carrier transport properties offer advantages over conventional semiconductors in specialized operating regimes.
