Two dimensional (2D) metal-semiconductor heterostructures are promising for high-performance optoelectronic devices due to fast carrier separation and transportation. Considering the superior metallic characteristics accompanied by high electrical conductivity in NbSe2, surface oxidation provides a facile way to form NbSe2/Nb2O5 metal-semiconductor heterostructures. Herein, size-dependent NbSe2/Nb2O5 nanosheets were achieved by a liquid phase exfoliation method and a gradient centrifugation strategy. These NbSe2/Nb2O5 heterostructure-based photodetectors show high responsivity with 23.21 μA W−1, fast response time of millisecond magnitude, and wide band detection ability in the UV-Vis region. It is noticeable that the photocurrent density is sensitive to the surface oxygen layer due to the oxygen-sensitized photoconduction mechanism. The flexible testing of the NbSe2/Nb2O5 heterostructure-based PEC-type photodetectors exhibits high photodetection performance even after bending and twisting. Beyond that, the solid-state PEC-type NbSe2/Nb2O5 photodetector also achieves relatively stable photodetection and high stability. This work promotes the application of 2D NbSe2/Nb2O5 metal-semiconductor heterostructures in flexible optoelectronic devices.

Nanoscale Horizons
Nanoscale Horizons is a leading journal for the publication of exceptionally high-quality, innovative nanoscience and nanotechnology. The journal places an emphasis on original research that demonstrates a new concept or a new way of thinking (a conceptual advance), rather than primarily reporting technological improvements. However, outstanding articles featuring truly breakthrough developments such as record performance alone may also be published in the journal. For work to be published it must be of significant general interest to our community-spanning readership. Topics covered in the journal include, but are not limited to: Synthesis of nanostructured and nanoscale materials Quantum materials 2D materials Layered materials Layered quantum materials Characterisation of functional nanoscale materials and bio-assemblies Properties of nanoscale materials Self-assembly and molecular organisation Complex hybrid nanostructures Nanocomposites, nanoparticles, nanocrystalline materials, and nanoclusters Nanotubes, molecular nanowires and nanocrystals Molecular nanoscience Nanocatalysis Theoretical modelling Single-molecules Plasmonics Nanoelectronics and molecular electronics Nanophotonics Nanochips, nanosensors, nanofluidics and nanofabrication Carbon-based nanoscale materials and devices Biomimetic materials Nanobiotechnology/bionanomaterials Nanomedicine Regulatory approaches and risk assessment
