TL;DR: A stretchable multisensor system is successfully demonstrated with an integrated energy-storage device, an array of microsupercapacitors that can be repeatedly charged via a wireless radio-frequency power receiver on the same stretchable polymer substrate.
Journal ArticleDOI
Defect-engineered graphene chemical sensors with ultrahigh sensitivity
TL;DR: This study revealed that defect engineering in graphene has significant potential for fabricating ultra-sensitive graphene chemical sensors and systematically investigated the mechanism of gas sensing, which indicated that the vacancy defect is a major contributing factor to the enhanced sensitivity.
Journal ArticleDOI
Influence of High-Energy Proton Irradiation on β-Ga2O3 Nanobelt Field-Effect Transistors
TL;DR: The radiation-induced damage in the β-Ga2O3-based FETs was significantly recovered after rapid thermal annealing at 500 °C, rendering it a promising building block for space applications.
Journal ArticleDOI
High breakdown voltage quasi-two-dimensional β-Ga2O3 field-effect transistors with a boron nitride field plate
TL;DR: In this article, a β-Ga2O3 metal-semiconductor field effect transistor (MESFET) with a high off-state breakdown voltage (344 V) based on a quasi-two-dimensional field-plated with hexagonal boron nitride (h-BN) was demonstrated.
