Abstract
A novel visible-light-absorbing dilute alloy, Ga(Sbx)N1-x is synthesized by metal organic chemical vapor deposition (MOCVD) for solar hydrogen production. Significant bandgap reduction of GaN, from 3.4 eV to 1.8 eV, is observed, with a low (2%) incorporation of antimonide, and the lattice expansion is in agreement with our first-principles calculations. The band edges of Ga(Sbx)N1-x are found to straddle the water redox potentials showing excellent suitability for solar water splitting.Entities:
