Abstract

Tantalum nitride (Ta$_3$N$_5$) is a promising semiconductor for solar-driven photoelectrochemical (PEC) water splitting, but its performance is limited by intrinsic defects. Here, we investigate the effect of titanium (Ti) doping (0–10 at%) on the structural, compositional, and optoelectronic properties of Ta$_3$N$_5$ thin films. At low concentrations (
