Effect of an indium-tin-oxide overlayer on transparent Ni/Au ohmic contact on p-type GaN
TL;DR: In this paper, a low-resistant, thermally stable, and transparent ohmic contact on p-type GaN using an indium-tinoxide (ITO) overlayer on Ni/Au contact was reported.
Journal ArticleDOI
Recent Advances in Electrochemical Sensors and Biosensors for Detecting Bisphenol A.
Somayeh Tajik,Hadi Beitollahi,Fariba Garkani Nejad,Kaiqiang Zhang,Quyet Van Le,Ho Won Jang,Soo Young Kim,Mohammadreza Shokouhimehr +7 more
TL;DR: Diverse chemically modified electrodes using various substances that have been reported in numerous studies in the recent decade for use in electrochemical sensors and biosensors to detect BPA are critically evaluated.
Journal ArticleDOI
Transparent Ohmic contacts of oxidized Ru and Ir on p-type GaN
Ho Won Jang,Jong-Lam Lee +1 more
TL;DR: In this article, low-resistance, high-transparency, and thermally stable Ohmic contacts on p-type GaN were achieved using Ru and Ir. Oxidation annealing under O2 atmosphere led to the reduction of contact resistivity by greater than one order of magnitude, compared to N2.
Journal ArticleDOI
Au decoration of a graphene microchannel for self-activated chemoresistive flexible gas sensors with substantially enhanced response to hydrogen
Yeon Hoo Kim,Yeon Hoo Kim,Yongseok Choi,Seo Yun Park,Taehoon Kim,Seung-Pyo Hong,Tae Hyung Lee,Cheon Woo Moon,Jong Heun Lee,Donghwa Lee,Byung Hee Hong,Ho Won Jang +11 more
TL;DR: An unexpected substantial enhancement in H2 detection is found, which has never been reported for Au decoration on any type of chemoresistive material, and holds the key to diverse research areas based on metal nanocluster/graphene heterostructures.
Journal ArticleDOI
Vertically ordered SnO2 nanobamboos for substantially improved detection of volatile reducing gases
Jong Myeong Jeon,Young Seok Shim,Su Deok Han,Do Hong Kim,Yeon Hoo Kim,Chong Yun Kang,Jin Sang Kim,Miyoung Kim,Ho Won Jang +8 more
TL;DR: In this article, the highly ordered SnO2 nanorods with Au nanoparticles are synthesized by a glancing-angle deposition technique, which enable them to detect sub-ppb levels of volatile reducing gases with a fast response speed.
