Temperature Sensors Integrated into a CMOS Image Sensor

open access: yesProceedings, 2017
In this work, a novel approach is presented for measuring relative temperature variations inside the pixel array of a CMOS image sensor itself. This approach can give important information when compensation for dark (current) fixed pattern noise (FPN) is

Defects formation on the surface of Si-substrates during thermal sputtering of gold

open access: yesТехнологія та конструювання в електронній апаратурі, 2023
Silicon photodetectors, in particular p–i–n photodiodes, are widely used as sensors of optical radiation. With technological advances, the requirements for the parameters and reliability of these elements of solid-state electronics are increasing sharply,

Carrier scattering approach to the origins of dark current in mid- and far-infrared (terahertz) quantum-well intersubband photodetectors (QWIPs) [PDF]

open access: yes, 2001
A carrier scattering approach is taken in an analysis of the affect on the dark current of extending the operating wavelength of conventional bound to continuum quantum-well intersubband photodetectors. It is found that both the sequential tunneling and

Particle Dark Matter Constraints from the Draco Dwarf Galaxy [PDF]

open access: yes, 2002
It is widely thought that neutralinos, the lightest supersymmetric particles, could comprise most of the dark matter. If so, then dark halos will emit radio and gamma ray signals initiated by neutralino annihilation.

A Physics-Based Analytical Model for Current–Voltage Characteristics of Perovskite Solar Cells Incorporating Bulk Recombination

open access: yesEnergies, 2021
A physics-based compact analytical model for studying the current–voltage characteristics of perovskite solar cells has been proposed by considering the external voltage-dependent carrier transport, exponential photon absorption, and bulk charge carrier ...

Anapole Dark Matter at the LHC [PDF]

open access: yes, 2014
The anapole moment is the only allowed electromagnetic moment for Majorana fermions. Fermionic dark matter acquiring an anapole can have a standard thermal history and be consistent with current direct detection experiments.
