Journal ArticleDOI
Fracture characteristics of monolayer CVD-graphene.
Yun Hwangbo,Choong Kwang Lee,Sang-Min Kim,Jae-Hyun Kim,Kwang-Seop Kim,Bongkyun Jang,Hak-Joo Lee,Seoung-Ki Lee,Seong Su Kim,Jong Hyun Ahn,Seung Mo Lee +10 more
TL;DR: The results imply that the CVD-graphene could be an ideal candidate as a structural material notwithstanding environmental susceptibility, and suggest that specific non-continuum fracture behaviors occurring in 2D monoatomic structures can be macroscopically well visualized and characterized.
Journal ArticleDOI
Flexible, transparent single-walled carbon nanotube transistors with graphene electrodes.
TL;DR: A mechanically flexible, transparent thin film transistor that uses graphene as a conducting electrode and single-walled carbon nanotubes (SWNTs) as a semiconducting channel is reported.
Journal ArticleDOI
Local Strain Induced Band Gap Modulation and Photoluminescence Enhancement of Multilayer Transition Metal Dichalcogenides
Krishna P. Dhakal,Shrawan Roy,Houk Jang,Xiang Chen,Won Seok Yun,Hyunmin Kim,Jae Dong Lee,Jeongyong Kim,Jong Hyun Ahn +8 more
TL;DR: In this article, the authors reported on the local strain engineering and tuning of an electronic band structure of TMDs multilayer films along the K−Γ line by artificially creating one-dimensional wrinkle structures.
Journal ArticleDOI
Ultrathin organic solar cells with graphene doped by ferroelectric polarization.
Keumok Kim,Sang-Hoon Bae,Chee Tat Toh,Hobeom Kim,Jeong Ho Cho,Dongmok Whang,Tae-Woo Lee,Barbaros Özyilmaz,Jong Hyun Ahn +8 more
TL;DR: An effective method to improve the performance and long-term stability of graphene-based OSCs using electrostatically doped graphene films via a ferroelectric polymer is reported.
Journal ArticleDOI
Fabrication of metallic nanomesh: Pt nano-mesh as a proof of concept for stretchable and transparent electrodes
TL;DR: In this article, two-dimensional ordered arrays of honeycomb morphology of platinum are fabricated by using anodized aluminum oxide template and metal sputtering methods, and the resulting metal films are highly conductible and stretchable.
