Strain-engineered indirect-to-direct band gap transition, photocatalytic water splitting activity, and optical responses in ACuGa6S10 (A = Rb and Cs)
Chalcogenide semiconductors have emerged as promising candidates for photocatalytic (PC) hydrogen evolution and optoelectronic applications, owing to their tunable band gaps (Eg) and favorable band edge alignments, rendering them indispensable for clean and carbon-free energy technologies. This study presents the first...
