The novel 2D-3D In2O3 homojunction with a suitable energy band alignment achieves high-performance self-powered UV detection.

Caption

2D nanosheets upshift the conductive band and Fermi level stemming from the oxygen vacancy. The boosted photoresponse of 2D-3D homojunction is attributed to the strong built-in electric field and more electrochemically active sites, leading to higher photogenerated carrier separation efficiency and faster interfacial charge transfer.
