Journal ArticleDOI
Interaction of 2D materials with liquids: wettability, electrochemical properties, friction, and emerging directions
TL;DR: In this paper, the authors discuss the wettability, electrical double layer (EDL) structure, and frictional interactions originating from 2D material-liquid interactions, and conclude that the EDL modulation partially explains the wetability modulation and enables distinctive electrofluidic systems.
Journal ArticleDOI
Reversible and Irreversible Responses of Defect-Engineered Graphene-Based Electrolyte-Gated pH Sensors.
Sun Sang Kwon,Jaeseok Yi,Won Woo Lee,Jae Hyeok Shin,Su Han Kim,Seunghee H. Cho,SungWoo Nam,Won Il Park +7 more
TL;DR: Although the H(+) ion binding to the defects increased the device response to pH change, this binding was found to be irreversible, and the irreversible component showed relatively fast decay, almost disappearing after 5 cycles of exposure to solutions of decreasing pH value.
Journal ArticleDOI
Highly Strain-Tunable Interlayer Excitons in MoS2/WSe2 Heterobilayers.
Chullhee Cho,Joeson Wong,Amir Taqieddin,Souvik Biswas,Narayana R. Aluru,SungWoo Nam,Harry A. Atwater +6 more
TL;DR: In this article, the effects of mechanical strain on the optoelectronic properties of interlayer excitons in heterobilayers of transition-metal dichalcogenides (TMDCs) remain relatively uncharacterized.
Journal ArticleDOI
Rapid Stencil Mask Fabrication Enabled One-Step Polymer-Free Graphene Patterning and Direct Transfer for Flexible Graphene Devices
TL;DR: It is demonstrated that the polymer-free approach for both patterning and transfer to flexible substrates allows the realization of cleaner graphene features as confirmed by water contact angle measurements.
Journal ArticleDOI
High-Mobility MoS2Directly Grown on Polymer Substrate with Kinetics-Controlled Metal-Organic Chemical Vapor Deposition
Jihun Mun,Hyeji Park,Jaeseo Park,DaeHwa Joung,DaeHwa Joung,Seoung-Ki Lee,Juyoung Leem,Jae Min Myoung,Jonghoo Park,Soo-Hwan Jeong,Won Chegal,SungWoo Nam,Sang Woo Kang,Sang Woo Kang +13 more
TL;DR: Batch growth of highmobility (μFE > 10 cm2V 1s−1) molybdenum disulfide (MoS2) films can be achieved by means of the chemical vapor deposition (CVD) method at high temperatures (>500 °C) on rigid s...
