Journal ArticleDOI
Roll-to-roll production of 30-inch graphene films for transparent electrodes
Sukang Bae,Hyeongkeun Kim,Youngbin Lee,Xiangfan Xu,Jaesung Park,Yi Zheng,Jayakumar Balakrishnan,Tian Lei,Hye Ri Kim,Young Il Song,Young Jin Kim,Kwang S. Kim,Barbaros Özyilmaz,Jong Hyun Ahn,Byung Hee Hong,Sumio Iijima,Sumio Iijima +16 more
TL;DR: The roll-to-roll production and wet-chemical doping of predominantly monolayer 30-inch graphene films grown by chemical vapour deposition onto flexible copper substrates are reported, showing high quality and sheet resistances superior to commercial transparent electrodes such as indium tin oxides.
Journal ArticleDOI
Extremely efficient flexible organic light-emitting diodes with modified graphene anode
Tae Hee Han,Youngbin Lee,Mi Ri Choi,Seonghoon Woo,Sang-Hoon Bae,Byung Hee Hong,Jong Hyun Ahn,Tae-Woo Lee +7 more
TL;DR: In this paper, a high-work-function, low-sheet-resistance graphene anode was used to improve the luminous efficiency of organic light-emitting diodes (OLEDs).
Journal ArticleDOI
Wafer-Scale Synthesis and Transfer of Graphene Films
Youngbin Lee,Sukang Bae,Houk Jang,Sukjae Jang,Shou En Zhu,Sung Hyun Sim,Young Il Song,Byung Hee Hong,Jong Hyun Ahn +8 more
TL;DR: Methods to produce wafer scale, high-quality graphene films as large as 3 in.
Journal ArticleDOI
High-Performance Perovskite–Graphene Hybrid Photodetector
Youngbin Lee,Jeong Kwon,Euyheon Hwang,Chang Ho Ra,Won Jong Yoo,Jong Hyun Ahn,Jong Hyeok Park,Jeong Ho Cho +7 more
TL;DR: A high-performance novel photodetector is demonstrated, which consists of graphene and CH3 NH3 PbI3 perovskite layers that exhibits a dramatically enhanced photo responsivity and effective quantum efficiency over a broad bandwidth within the UV and visible ranges.
Journal ArticleDOI
Graphene-based transparent strain sensor
TL;DR: Transparent strain sensors based on graphene were fabricated in a form of rosette on a flexible plastic or stretchable rubber substrate by using reactive ion etching and stamping techniques.
