Electrothermal Evaluation of AlGaN/GaN Membrane High Electron Mobility Transistors by Transient Thermoreflectance

open access: yesIEEE Journal of the Electron Devices Society, 2018
A novel wet etch process for fabrication of large-area AlGaN/GaN membranes is reported, along with an evaluation of membrane-high electron mobility transistor (HEMT) electrothermal performance up to 1.9 W/mm. Hall measurements showed negligible post-etch

Development of Catalytic-CVD SiNx Passivation Process for AlGaN/GaN-on-Si HEMTs

open access: yesCrystals, 2020
We optimized a silicon nitride (SiNx) passivation process using a catalytic-chemical vapor deposition (Cat-CVD) system to suppress the current collapse phenomenon of AlGaN/GaN-on-Si high electron mobility transistors (HEMTs).

Current Collapse Phenomena Investigation in Automotive-Grade Power GaN Transistors

open access: yesEnergies, 2023
This work analyzes the impact of working conditions on the current collapse (CC) phenomenon for an automotive GaN device. For this purpose, some sensing circuits have been compared to find the most suitable for the considered GaN family.

Analysis and improvement of self-heating effect based on GaN HEMT devices

open access: yesMaterials Research Express, 2022
Gallium nitride high electron mobility transistor (GaN HEMT) applications in high-power and high-frequency environments can lead to high device temperatures due to the self-heating effect, thus limiting device performance and reliability.

Benefits of Objective Collapse Models for Cosmology and Quantum Gravity [PDF]

open access: yes, 2013
We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applications of objective reduction models to three important issues: the origin of ...

Parametric plastic collapse loads and their validation for horizontal saddle supported storage vessels [PDF]

open access: yes, 2003
In general, progressive plastic collapse occurs in vessels with low values of R/t ratio, typically less than 200, and elastic-plastic buckling is observed in vessels with higher R/t ratios. The aim of this paper is to examine various theoretical analyses

High Figure-of-Merit ( ${V}_{\text{BR}}^{\text{2}}$ / ${R}_{\text{ON}}$ ) AlGaN/GaN Power HEMT With Periodically C-Doped GaN Buffer and AlGaN Back Barrier

open access: yesIEEE Journal of the Electron Devices Society, 2018
In this paper, we investigated characteristics of AlGaN/GaN high-electron mobility transistors (HEMTs) with high resistive buffer structure consisted of periodically carbon-doped (PCD) GaN buffer layer and AlGaN back barrier layer.

Threat-Independent Column Removal and Fire-Induced Progressive Collapse: Numerical Study and Comparison [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2015
Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it.
