Low Buffer Trapping Effects above 1200 V in Normally off GaN-on-Silicon Field Effect Transistors

Micromachines, 2022
We report on the fabrication and electrical characterization of AlGaN/GaN normally off transistors on silicon designed for high-voltage operation. The normally off configuration was achieved with a p-gallium nitride (p-GaN) cap layer below the gate ...

Analysis of Anti-JFET for 600V VDMOS and HCI Reliability

MATEC Web of Conferences, 2018
In VDMOS device the anti-JFET concentration has important role for determining the breakdown voltage and on-resistance of the device. Because higher N-drift doping concentration can provide the very best on-resistance of the device but also decrease ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
