Journal ArticleDOI
Monolayer Co3O4 Inverse Opals as Multifunctional Sensors for Volatile Organic Compounds
Chul Soon Lee,Zhengfei Dai,Seong Yong Jeong,Chang Hoon Kwak,Boyoung Kim,Do Hong Kim,Do Hong Kim,Ho Won Jang,Joon-Shik Park,Jong Heun Lee +9 more
TL;DR: Unprecedentedly high ethanol response and temperature-modulated control of selectivity with respect to ethanol, xylene, and methyl benzenes were attributed to the highly chemiresistive IO nanoarchitecture and to the tuned catalytic promotion of different gas-sensing reactions, respectively.
Journal ArticleDOI
Observation of physisorption in a high-performance FET-type oxygen gas sensor operating at room temperature
Seongbin Hong,Jongmin Shin,Yoonki Hong,Meile Wu,Dongkyu Jang,Yujeong Jeong,Gyuweon Jung,Jong-Ho Bae,Ho Won Jang,Jong-Ho Lee +9 more
TL;DR: It is reported, for the first time, that the performance of a field effect transistor (FET)-type O2 sensor operating at 25 °C was improved greatly by a physisorption sensing mechanism.
Journal ArticleDOI
Thermally stable Ir Schottky contact on AlGaN/GaN heterostructure
TL;DR: In this article, the Schottky barrier height was increased from 0.68 to 1.07 eV, and the reverse leakage current dramatically decreased after annealing at 500 °C under O2 ambient.
Journal ArticleDOI
NO2 sensing properties of porous Au-incorporated tungsten oxide thin films prepared by solution process
Taehoon Kim,Amirhossein Hasani,Le Van Quyet,Le Van Quyet,Yeon Hoo Kim,Seo Yun Park,Mi Gyoung Lee,Woonbae Sohn,Thang Phan Nguyen,Kyoung Soon Choi,Soo Young Kim,Ho Won Jang +11 more
TL;DR: In this paper, the authors developed a facile method to fabricate a gas sensor based on porous Au-incorporated tungsten trioxide (WO3) thin films for highly sensitive and selective NO2 sensing.
Journal ArticleDOI
Solution-Processed Metal Oxide Thin Film Nanostructures for Water Splitting Photoelectrodes: A Review
TL;DR: In this paper, a review of recent challenges for various nanostructured oxide photoelectrodes fabricated by solution-based processes is presented, and an outlook on eco-friendly and cost-effective approaches to solar fuel generation and innovative artificial photosynthesis technologies is given.
