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
Energy band-gap engineering of graphene nanoribbons.
TL;DR: It is found that the energy gap scales inversely with the ribbon width, thus demonstrating the ability to engineer the band gap of graphene nanostructures by lithographic processes.
Journal ArticleDOI
Current saturation in zero-bandgap, top-gated graphene field-effect transistors.
TL;DR: The first observation of saturating transistor characteristics in a graphene field-effect transistor is reported, demonstrating the feasibility of two-dimensional graphene devices for analogue and radio-frequency circuit applications without the need for bandgap engineering.
Journal ArticleDOI
Electric field effect in ultrathin black phosphorus
TL;DR: In this paper, the authors demonstrate few-layer black phosphorus field effect devices on Si/SiO2 and measure charge carrier mobility in a four-probe configuration as well as drain current modulation in a two-point configuration.
Journal ArticleDOI
Graphene for Controlled and Accelerated Osteogenic Differentiation of Human Mesenchymal Stem Cells
Tapas R. Nayak,Henrik Andersen,Venkata S. Makam,Clement Khaw,Sukang Bae,Xiangfan Xu,Pui Lai Rachel Ee,Jong Hyun Ahn,Byung Hee Hong,Giorgia Pastorin,Giorgia Pastorin,Barbaros Özyilmaz,Barbaros Özyilmaz +12 more
TL;DR: It is shown that graphene provides a promising biocompatible scaffold that does not hamper the proliferation of human mesenchymal stem cells and accelerates their specific differentiation into bone cells, demonstrating graphene's potential for stem cell research.
