KTaO2S
semiconductor· KTaO2S
KTaO₂S is a mixed-anion semiconductor compound combining potassium, tantalum, oxygen, and sulfur in an anionic framework structure. This is a research-stage material being investigated for photocatalytic and optoelectronic applications, as the substitution of oxygen with sulfur can modulate the bandgap and enhance light-absorption properties compared to oxide-only tantalates. The material represents an emerging class of oxysulifdes with potential relevance to solar energy conversion, environmental remediation, and next-generation semiconductor device development.
