Ni4 As4 Se4

Ni₄As₄Se₄ is a quaternary semiconductor compound belonging to the nickel-based chalcogenide family, combining nickel with arsenic and selenium elements in a layered or 3D crystal structure. This material remains largely in the research phase, with primary interest in optoelectronic and thermoelectric applications where its narrow bandgap and mixed-anion composition offer tunable electronic properties. Engineers would consider it as an alternative to more conventional semiconductors (like GaAs or CdTe) in exploratory projects targeting infrared detection, energy conversion devices, or niche electronic applications where the specific combination of nickel-arsenic-selenium bonding provides advantages in band structure engineering or thermal management.
