2D materials broadband photodetectors


Our review provides a comprehensive overview on the latest evolution of broadband photodetectors (BBPDs) based on 2D materials (2DMs). We begin with BBPDs built on various 2DM channels, including narrow-bandgap 2DMs, 2D topological semimetals, 2D charge density wave compounds, and 2D heterojunctions. Then, we introduce defect-engineered 2DM BBPDs, including vacancy engineering, heteroatom incorporation, and interfacial engineering. Subsequently, we summarize 2DM based mixed-dimensional (0D–2D, 1D–2D, 2D–3D, 0D–2D–3D) BBPDs. Finally, we provide several viewpoints for the future development of this burgeoning field.
