Improvement of Gas-Sensing Performance of Large-Area Tungsten Disulfide Nanosheets by Surface Functionalization
Kyung Yong Ko,Jeong Gyu Song,Youngjun Kim,Taejin Choi,Sera Shin,Chang Wan Lee,Kyounghoon Lee,Jahyun Koo,Hoonkyung Lee,Jongbaeg Kim,Taeyoon Lee,Jusang Park,Hyungjun Kim +12 more
TL;DR: This work demonstrates the improvement of gas-sensing performance of large-area tungsten disulfide (WS2) nanosheets through surface functionalization using Ag nanowires (NWs) to improve 2D TMDC gas sensors.
Journal ArticleDOI
Controllable synthesis of molybdenum tungsten disulfide alloy for vertically composition-controlled multilayer
Jeong Gyu Song,Gyeong Hee Ryu,Su Jeong Lee,Sangwan Sim,Chang Wan Lee,Taejin Choi,Hanearl Jung,Youngjun Kim,Zonghoon Lee,Jae Min Myoung,Christian Dussarrat,Clement Lansalot-Matras,Jusang Park,Hyunyong Choi,Hyungjun Kim +14 more
TL;DR: Spectroscopic and microscopic results indicate that the synthesized Mo1−xWxS2 alloys have complete mixing of Mo and W atoms and tunable band gap by systematically controlled composition and layer number.
Journal ArticleDOI
Low-temperature synthesis of 2D MoS2 on a plastic substrate for a flexible gas sensor
Yuxi Zhao,Jeong Gyu Song,Gyeong Hee Ryu,Kyung Yong Ko,Whang Je Woo,Youngjun Kim,Dong-Hyun Kim,Jun Hyung Lim,Sunhee Lee,Zonghoon Lee,Jusang Park,Hyungjun Kim +11 more
TL;DR: MoS2 produced by low-temperature CVD was determined to possess a layered structure with good uniformity, stoichiometry, and a controllable number of layers, which has potential for burgeoning flexible and wearable nanotechnology applications.
Journal ArticleDOI
Recovery Improvement for Large-Area Tungsten Diselenide Gas Sensors
Kyung Yong Ko,Kyunam Park,Sangyoon Lee,Youngjun Kim,Whang Je Woo,Dong-Hyun Kim,Jeong Gyu Song,Jusang Park,Hyungjun Kim +8 more
TL;DR: Improved recovery of the WSe2 gas sensor's NO2-sensing performance by utilizing external thermal energy is demonstrated by reacting NH3 and adsorbed NO2 on the surface of WSe1 and the recovery time is dramatically decreased.
Journal ArticleDOI
2D Transition Metal Dichalcogenide Heterostructures for p- and n-Type Photovoltaic Self-Powered Gas Sensor
