Highly sensitive and selective room-temperature NO2 gas-sensing characteristics of SnOX-based p-type thin-film transistor
TL;DR: In this article, a p-type MOS-based thin-film transistor (TFT) nitrogen dioxide (NO2) gas sensor that used tin oxide (SnOX) for both the channel and sensing layers was demonstrated.
Journal ArticleDOI
Low temperature NO2 sensing properties of RF-sputtered SnO-SnO2 heterojunction thin-film with p-type semiconducting behavior
TL;DR: In this article, a high-performance p-type semiconducting gas sensor was successfully fabricated based on a SnO-SnO2 p-n heterojunction thin-film formed via a radio-frequency (RF) -magnetron sputtering process.
Journal ArticleDOI
Strain-relaxed GeSn-on-Insulator (GeSnOI) microdisks
TL;DR: In this paper, a dual insulator GeSn-on-insulator (GeSnOI) material platform was developed to produce strain-relaxed GeSn microdisks stuck on a substrate, which achieved three key properties for a highperformance GeSn laser: removal of harmful compressive strain, decent thermal management, and excellent optical confinement.
