Dark Current Noise Correction Method Based on Dark Pixels for LWIR QWIP Detection Systems
Applied Sciences, 2022 The long-wave infrared (LWIR) quantum-well photodetector (QWIP) operates at low temperatures, but is prone to focal plane temperature changes when imaging in complex thermal environments.

Photostability Improvement of Organic Photodiodes with ZnO Electron Transport Layer
Advanced Photonics Research, 2023 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 ...

Absorption of fermionic dark matter by nuclear targets [PDF]
, 2020 Absorption of fermionic dark matter leads to a range of distinct and novel signatures at dark matter direct detection and neutrino experiments. We study the possible signals from fermionic absorption by nuclear targets, which we divide into two classes ...

Turning off the Lights: How Dark is Dark Matter? [PDF]
, 2010 We consider current observational constraints on the electromagnetic charge of dark matter. The velocity dependence of the scattering cross-section through the photon gives rise to qualitatively different constraints than standard dark matter scattering ...
