Optimizing optical absorption of TiO[sub 2] by alloying with TiS[sub 2]
Naoto Umezawa, Anderson Janotti, Patrick Rinke, Toyohiro Chikyow, and Chris G. Van de Walle
TiO is an attractive material for photocatalytic water splitting, but its band gap is too large to allow for efficient absorption of solar photons. We present a comprehensive first-principles investigation of band-structure modifications induced by alloying TiO with TiS. The band gap of TiOS alloys ... [Appl. Phys.
