Strain-balanced Si/SiGe type-II superlattices for near-infrared photodetection

Applied Physics Letters, 2014
Strain balanced silicon-silicon germanium type-II superlattice p-i-n photodetectors grown on a silicon germanium relaxed buffer layer are shown to exhibit an absorption band that extends beyond 0.7 eV (λ = 1.77 μm) with dark current densities of 27 μA cm−2.

Au–PbS core–shell nanorods for plasmon-enhanced near-infrared photodetection

Journal of Materials Science, 2019
Plasmonic metals possess the ability to enhance the interaction between light and matter, which has been widely used in optoelectronic devices, especially, a direct contact is established between metal and semiconductor in hetero-nanostructure. In this work, we report an enhanced photodetector by surface plasmon, which is based on Au–PbS core–shell ...

Type-II InGaAs/GaAsSb superlattice for photodetection in the near infrared

SPIE Proceedings, 2002
The optical properties of an (formula available in paper) type-II superlattice lattice matched to InP(001) was characterized by photo luminescence and near infrared photoresponse. The samples were designed for optical emission near 1.8micrometers and were grown by molecular beam epitaxy.

Enhancement of MoTe2 near-infrared absorption with gold hollow nanorods for photodetection

Nano Research, 2020
Infrared (IR) light photodetection based on two dimensional (2D) materials of proper bandgap has attracted increasing attention. However, the weak IR absorption in 2D materials, due to their ultrathin attribute and indirect bandgap in multilayer structures, degrades their performance when used as IR photodetectors.

Enhanced Near‐Infrared Photodetection in a Mixed‐Dimensional 0D/2D Heterostructure via Two‐Photon Absorption

Laser & Photonics Reviews
The perovskite nanocrystals (NCs) are featured with a strong two‐photon absorption (TPA) due to the quantum‐confinement effect, but suffer from a short transport distance of the photogenerated charge carriers isolated within the 0D spatial volumes.
