· Be1 K4 As2

Be₁K₄As₂ is a ternary semiconductor compound combining beryllium, potassium, and arsenic. This material is primarily of research and exploratory interest rather than established industrial production, belonging to the broader family of III-V and mixed-valence semiconductors. It represents a compound system where the unusual combination of alkali metal (potassium) with group II and group V elements creates potential for novel electronic or optoelectronic properties that differ from conventional binary semiconductors.
