6.2 210ke− Saturation signal 3µm-pixel variable-sensitivity global-shutter organic photoconductive image sensor for motion capture Abstract: Image sensors for applications such as machine vision, in-vehicle cameras, and surveillance cameras require a global shutter (GS) function.
Graphene/Ge Photoconductive Position-Sensitive Detectors …
2023年1月12日 · In this paper, a photoconductive type of PSD based on graphene/Ge heterojunction by using the charge injection effect is presented. Under near-infrared illumination, the photogenerated carriers in Ge diffuse laterally to the graphene/Ge heterojunction region and then inject into graphene.
Photomultiplier Tubes (PMTS) are light detectors that are useful in low intensity applications such as fluorescence spectroscopy. Due to high internal gain, PMTs are very sensitive detectors. A pure semiconductor is a poor electrical conductor as a consequence of having just the right number of electrons to completely fill its valence bonds.
Broadband infrared photodetection using a narrow bandgap
2021年6月9日 · We report high-performance infrared photodetection from a donor-acceptor conjugated polymer with broadband SWIR-LWIR operation. Electronic correlations within the π-conjugated backbone promote a high-spin ground state, narrow bandgap, long-wavelength absorption, and intrinsic electrical conductivity.

Photoconductive Detectors – intrinsic, extrinsic, design, thermal ...
Photoconductive antennas are often used to detect terahertz radiation. Although such devices can also be called photoconductive detectors, in this article we consider only detectors for light, i.e., electromagnetic radiation with much higher optical frequencies. An important distinction is that between intrinsic and extrinsic photoconductors:
Negative Photoconductive Effect for Novel Photoelectric Sensors…
2024年12月4日 · Most studies on photoconductance sensors focus on positive photoconductivity (PPC); however, rare cases exist in which the conductivity decreases under light exposure. Such cases are known as negative photoconductivity (NPC).
