Dark Current Modeling for a Polyimide—Amorphous Lead Oxide-Based Direct Conversion X-ray Detector [PDF]
Sensors, 2022 The reduction of the dark current (DC) to a tolerable level in amorphous selenium (a-Se) X-ray photoconductors was one of the key factors that led to the successful commercialization of a-Se-based direct conversion flat panel X-ray imagers (FPXIs) and ...

Proximity Gettering Design of Hydrocarbon–Molecular–Ion–Implanted Silicon Wafers Using Dark Current Spectroscopy for CMOS Image Sensors [PDF]
Sensors, 2019 We developed silicon epitaxial wafers with high gettering capability by using hydrocarbon−molecular−ion implantation. These wafers also have the effect of hydrogen passivation on process-induced defects and a barrier to out-diffusion of ...

Correction of dark current in consumer cameras
Journal of Electronic Imaging, 2010 A study of dark current in digital imagers in digital single- lens reflex (DSLR) and compact consumer-grade digital cameras is presented. Dark current is shown to vary with temperature, expo- sure time, and ISO setting. Further, dark current is shown to in- crease in successive images during a series of images.

Analysis of Dark Current in BRITE Nanostellite CCD Sensors. [PDF]
Sensors (Basel), 2018 The BRightest Target Explorer (BRITE) is the pioneering nanosatellite mission dedicated for photometric observations of the brightest stars in the sky. The BRITE charge coupled device (CCD) sensors are poorly shielded against extensive flux of energetic particles which constantly induce defects in the silicon lattice.

Carrier Transport Control for Enhanced Performance in Dual-Color Quantum Well Infrared Photodetectors [PDF]
NanomaterialsInfrared photodetectors are important for military, medical, and environmental applications. Dual-color quantum well infrared photodetectors (QWIPs) are attractive because they can provide multi-spectral information, but their performance is often ...

Dark current measurements in a CMOS imager
SPIE Proceedings, 2008 We present data for the dark current of a commercially available CMOS image sensor for different gain settings and bias offsets over the temperature range of 295 to 340 K and exposure times of 0 to 500 ms. The analysis of hot pixels shows two different sources of dark current.

Dark current behavior in DSLR cameras
SPIE Proceedings, 2009 Digital single-lens reflex (DSLR) cameras are examined and their dark current behavior is presented. We examine the influence of varying temperature, exposure time, and gain setting on dark current. Dark current behavior unique to sensors within such cameras is observed.

Development of Low Parasitic Light Sensitivity and Low Dark Current 2.8 μm Global Shutter Pixel [PDF]
Sensors, 2018 : We developed a low parasitic light sensitivity (PLS) and low dark current 2.8 μm global shutter pixel. We propose a new inner lens design concept to realize both low PLS and high quantum efficiency (QE).

Simulating dark current in NLC structures [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006 Dark current generation and capture are of great importance in high gradient accelerating structure R&D especially for the NLC which aims to operate at 65 MV/m with specific limits on dark current and RF breakdown rates. Although considerable effort has been devoted to building and testing various types of structures to meet these requirements, few ...
