Dark Current Modeling for a Polyimide—Amorphous Lead Oxide-Based Direct Conversion X-ray Detector [PDF]
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]
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 ...

Development of Low Parasitic Light Sensitivity and Low Dark Current 2.8 μm Global Shutter Pixel [PDF]
: 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).

The influence of the structure of guard rings on the dark currents of silicon p-i-n photodiodes
The article examines the influence of the guard rings (GR) system structure on the dark currents of responsive elements (RE) and the actual guard rings of silicon 4-element p-i-n photodiodes (PD). The samples were made on the basis of p-silicon by planar

Metastable Dark Current in BRITE Nano-Satellite Image Sensors
Dark current in charge-coupled devices (CCDs) is one of the most important sources of impulsive noise present in scientific images. While the dark current originating in the fabrication defects (mainly impurities) is stable and dependent only on ...

Photostability Improvement of Organic Photodiodes with ZnO Electron Transport Layer
The stable performance of organic photodiodes (OPDs) is crucial for realizing reliable photosensing and their facile integration into larger systems. However, OPDs with the commonly used ZnO electron transport layer (ETL) suffer from photoinstability ...
