TL;DR: A high-performance gas sensor constructed using atomic-layered MoS2 synthesised by chemical vapour deposition (CVD) was developed and the in situ PL characterisation of the changes in the peaks corresponding to charged trions and neutral excitons via gas adsorption processes was used to elucidate the mechanisms of charge transfer between theMoS2 and the gas molecules.
Journal ArticleDOI
Highly Efficient and Bendable Organic Solar Cells with Solution-Processed Silver Nanowire Electrodes
Myungkwan Song,Dae Sung You,Kyounga Lim,Sujin Park,Sunghoon Jung,Chang Su Kim,Dongho Kim,Do-Geun Kim,Jongk-Kuk Kim,Juyun Park,Yong-Cheol Kang,Jinhee Heo,Sung-Ho Jin,Jonghyun Park,Jae-Wook Kang +14 more
TL;DR: In this paper, a bendable organic solar cell was fabricated using solution-processed silver nanowire (Ag NW) electrodes, achieving power conversion efficiencies of 5.80 and 5.02% at a bending radius of 200 mm.
Journal ArticleDOI
Ultrasmooth, extremely deformable and shape recoverable Ag nanowire embedded transparent electrode
Sanggil Nam,Myungkwan Song,Dongho Kim,Byung Jin Cho,Hye Moon Lee,Jung-Dae Kwon,Sung-Gyu Park,Kee-Seok Nam,Yongsoo Jeong,Se-Hun Kwon,Yun Chang Park,Sung-Ho Jin,Jae-Wook Kang,Sung Jin Jo,Chang Su Kim +14 more
TL;DR: The fabrication of a flexible transparent electrode with superior mechanical, electrical and optical properties is demonstrated by embedding a AgNW film into a transparent polymer matrix and can produce electrodes with an ultrasmooth and extremely deformable transparent electrode that have sheet resistance and transmittance comparable to those of an ITO electrode.
Journal ArticleDOI
Graphene-based gas sensor: metal decoration effect and application to a flexible device
Byung Jin Cho,Jongwon Yoon,Myung Gwan Hahm,Dongho Kim,Ah Ra Kim,Yung Ho Kahng,Sangwon Park,Young-Joo Lee,Sung-Gyu Park,Jung-Dae Kwon,Chang Su Kim,Myungkwan Song,Yongsoo Jeong,Kee-Seok Nam,Heung Cho Ko +14 more
TL;DR: In this paper, the role of metal nanoparticles (NPs) on graphene-based devices was investigated in terms of gas-sensing characteristics of NO2 and NH3, and flexible gas sensing was also realized for future applications.
