Solution-processed hybrid perovskite photodetectors with high detectivity.

Photodetectors capture optical signals with a wide range of incident photon flux density and convert them to electrical signals instantaneously. They have many important applications including imaging, optical communication, remote control, chemical/biological sensing and so on. Currently, GaN, Si and InGaAs photodetectors are used in commercially available products. Here we demonstrate a novel...

Low Noise, High Detectivity Photodetectors based on Organic Materials

Organic photodetectors (OPDs) are potentially useful in many applications because of their light weight, flexibility and good form factors. Despite the high detectivities that have been frequently reported for OPDs recently, the application of these OPDs for weak light detection has been rarely demonstrated. In this thesis, low noise, high gain photodetectors based on organic and ZnO nanopartic...

Ultrasensitive photodetectors based on monolayer MoS<sub>2</sub>

Two-dimensional materials are an emerging class of new materials with a wide range of electrical properties and potential practical applications. Although graphene1 is the most wellstudied two-dimensional material, single layers of other materials, such as insulating BN (ref. 2) and semiconducting MoS2 (refs 3,4) or WSe2 (refs 5,6), are gaining increasing attention as promising gate insulators ...

Semiconducting Polymer Photodetectors with Electron and Hole Blocking Layers: High Detectivity in the Near-Infrared

Sensing from the ultraviolet-visible to the infrared is critical for a variety of industrial and scientific applications. Photodetectors with broad spectral response, from 300 nm to 1,100 nm, were fabricated using a narrow-band gap semiconducting polymer blended with a fullerene derivative. By using both an electron-blocking layer and a hole-blocking layer, the polymer photodetectors, operating...

Self-powered broadband, high-detectivity and ultrafast photodetectors based on Pd-MoS2/Si heterojunctions.

In this work, a self-powered photodetector device is fabricated through the integration of a palladium-doped molybdenum disulfide thin film on silicon (Pd-MoS2/Si). The substitution of host Mo atoms with Pd dopants in the MoS2 film is revealed by structural and chemical analysis techniques. Due to the incorporation of Pd atoms into the MoS2 films, the photovoltaic characteristics of the fabrica...
