· GaAs2W

GaAs2W is a gallium arsenide tungsten compound that falls within the metal or intermetallic family, combining a III-V semiconductor element (gallium arsenide) with tungsten. This material represents an experimental or specialized composition rather than a widely commercialized alloy, and is primarily of interest in research contexts exploring novel metallurgical or optoelectronic hybrid systems where tungsten's high-temperature stability and density are combined with GaAs properties.
