· Cu4 As8 O16

Cu₄As₈O₁₆ is an arsenic-copper oxide compound belonging to the family of mixed-valence metal arsenates, which are semiconducting materials of primary research interest rather than established commercial products. This compound is investigated in materials science and solid-state chemistry for its potential electronic and structural properties, with applications being explored in semiconductor device research and potentially in photovoltaic or photocatalytic systems where copper-based oxides show promise. The arsenic-containing composition makes it notable within the broader class of transition-metal arsenates, though engineering adoption remains limited to specialized research contexts due to the toxicity profile of arsenic and the relative immaturity of device integration pathways compared to more conventional semiconductor platforms.
