Planar Multilayered 2D GeAs Schottky Photodiode for High-Performance Visible–Near-Infrared Photodetection

ACS Applied Materials & Interfaces, 2021
Novel group IV - V 2D semiconductors (e.g., GeAs and SiAs) have arisen as an attractive candidate for broad-band photodetection and optoelectronic applications. This 2D family has a wide tunable band gap, excellent thermodynamic stability, and strong in-plane anisotropy.

Near Infrared Absorption Enhancement of Graphene for High-Responsivity Photodetection

2019 IEEE 16th International Conference on Group IV Photonics (GFP), 2019
Near-infrared strong light harvesting of graphene is obtained based on multipole resonance interference of silicon nanodisks. The ultrathin design allows the active area with effective generation of photo carriers, paving a new way for small footprint high-speed and high-responsivity photon detection.

Cocrystal Engineering: Toward Solution‐Processed Near‐Infrared 2D Organic Cocrystals for Broadband Photodetection

Angewandte Chemie International Edition, 2021
AbstractLarge‐area 2D cocrystals with strong near‐infrared (NIR) absorption have been designed and prepared. Driven by the intermolecular charge‐transfer (CT) interactions, zinc tetraphenylporphyrin (donor) and C60 (acceptor) self‐assemble into a NIR cocrystal with absorption wavelength up to 1080 nm. By tailoring the growth solvents and processes, the

Solution-processable phototransistor of PbS quantum dots/ZnO for highly responsive 1550 nm near infrared photodetection.

Journal of Colloid and Interface Science
Due to the low-cost in manufacturing and good compatibility with flexible substrate, lead sulfide quantum dots (PbS QDs) are increasingly regarded as a promising active material candidate for next-generation near-infrared (NIR) photodetectors.

Near-Infrared Photodetection with Molecular Beam Epitaxy Grown Extended InGaAs

MRS Proceedings, 2005
AbstractStrain-balanced InxGa1-xAs/InyGa1-yAs superlattices and fractional monolayer In0.532Ga0.468As/InAs superlattices were grown by solid-source molecular beam epitaxy (SSMBE) in order to extend the photodetection wavelength range beyond 1.7μm. Material qualities were characterized by transmitted electron microscope (TEM), X-ray diffraction (XRD ...

Sub‐Bandgap Photon Harvesting in Cu2AgBiI6 Perovskite Enabling Self‐Powered Near‐Infrared Photodetection

Laser & Photonics Reviews
Near‐infrared (NIR) photodetection has important applications in many fields. To improve NIR response in halide perovskites, two main approaches are reducing the bandgap or creating sub‐bandgap states through doping/alloying. In this study, the existence

Plasmonic Resonance Enhanced Polarization-Sensitive Photodetection by Black Phosphorus in Near Infrared

ACS Nano, 2018
Black phosphorus, a recently intensely investigated two-dimensional material, is promising for electronic and optoelectronic applications due to its higher mobility and thickness-dependent direct band gap. With its low direct band gap and anisotropic properties in nature, black phosphorus is also suitable for near-infrared polarization-sensitive ...
