HgTaO2N
semiconductor· HgTaO2N
HgTaO₂N is an experimental oxynitride semiconductor compound combining mercury, tantalum, oxygen, and nitrogen phases. This material belongs to the family of mixed-anion semiconductors under investigation for photocatalytic and photoelectrochemical applications, where the nitrogen doping of tantalum oxide is intended to narrow the bandgap and improve visible-light absorption compared to conventional TaO₂. While not yet commercialized, oxynitride semiconductors like this are being explored to enhance solar energy conversion efficiency and pollutant degradation under ambient lighting conditions.
