Abstract

Gallium selenide (GaSe) is a van der Waals semiconductor widely used for optoelectronic devices, whose performances are dictated by bulk properties, including band-gap energy. However, recent experimental observations that the exfoliation of GaSe into atomically thin layers enhances performances in electrochemistry and photocatalysis have apparently opened new avenues for its applications in the fields of energy and catalysis. Here, with surface-science experiments and density functional theory (DFT) we study the oxidation of GaSe into β-Ga2O3. The oxidation driven by Se vacancies, created in the exfoliation process, plays a pivotal role in the catalytic process.
