· Ta4 O1

Ta₄O₁₀ (tantalum oxide) is an oxygen-deficient ceramic semiconductor compound belonging to the tantalum oxide family, which exhibits mixed-valence electronic properties. This material is primarily investigated in research contexts for advanced electronic and photocatalytic applications, where its defect structure and semiconducting behavior offer potential advantages over stoichiometric tantalum pentoxide in devices requiring tunable bandgap or enhanced charge carrier properties.
