High-Uniformity and High Drain Current Density Enhancement-Mode AlGaN/GaN Gates-Seperating Groove HFET

IEEE Journal of the Electron Devices Society, 2018
In this paper, we report on a novel E-mode AlGaN/GaN gates-seperating groove heterostructure field-effect transistor (GSG HFET). The current turn-on/off is controlled by changing gate voltage to regulate the horizontal energy band between the double ...

The Drift Region Width Modulation Technique for Breakdown Performance Enhancement of AlGaN/GaN HEMT

IEEE Journal of the Electron Devices Society, 2022
The breakdown performance of the AlGaN/GaN high electron mobility transistor (HEMT) is limited by the high electric field peaks in the device. To obtain a more uniform electric field distribution, the drift region width modulation (DWM) technique is ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Cocoon-mimetic feature-matched interface for flexible system

npj Flexible Electronics
Flexible hybrid systems usually combine soft modules (mechanically matched with skin or clothes) and hard modulus (like rigid circuits). However, the risk of interface failure due to modulus mismatch between flexible components and rigid circuits limits ...
