Temperature Dependence of Electron and Hole Impact Ionization Coefficients in GaN

IEEE Transactions on Electron Devices, 2021
The temperature dependence of the electron and hole impact ionization coefficients in GaN has been investigated experimentally. Two types of p-i-n diodes grown on bulk GaN substrates have been fabricated and characterized, and the impact ionization ...

Impact Ionization Coefficient Prediction of a Lateral Power Device Using Deep Neural Network [PDF]

Micromachines, 2023
Nowadays, the impact ionization coefficient in the avalanche breakdown theory is obtained using 1-D PN junctions or SBDs, and is considered to be a constant determined by the material itself only.

Enhanced Responsivity of Photodetectors Realized via Impact Ionization

Sensors, 2012
To increase the responsivity is one of the vital issues for a photodetector. By employing ZnO as a representative material of ultraviolet photodetectors and Si as a representative material of visible photodetectors, an impact ionization process, in which

Temperature dependence of impact ionization in InAs

Optics Express, 2013
An Analytical Band Monte Carlo model was used to investigate the temperature dependence of impact ionization in InAs. The model produced an excellent agreement with experimental data for both avalanche gain and excess noise factors at all temperatures modeled. The gain exhibits a positive temperature dependence whilst the excess noise shows a very weak

Sb-Based Low-Noise Avalanche Photodiodes

Photonics, 2023
Accurate detection of weak optical signals is a key function for a wide range of applications. A key performance parameter is the receiver signal-to-noise ratio, which depends on the noise of the photodetector and the following electrical circuitry.

Optical and Thermal Behavior of Germanium Thin Films under Femtosecond Laser Irradiation

Nanomaterials, 2022
In this study, we theoretically investigate the response of a germanium thin film under femtosecond pulsed laser irradiation. Electron and lattice temperatures, as well as material-specific optical properties such as dielectric function and reflectivity,
