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
Spin–orbit proximity effect in graphene
Ahmet Avsar,Jun You Tan,Thiti Taychatanapat,Jayakumar Balakrishnan,Gavin Kok Wai Koon,Yuting Yeo,Jayeeta Lahiri,Alexandra Carvalho,Aleksandr Rodin,Eoin O'Farrell,Goki Eda,A. H. Castro Neto,Barbaros Özyilmaz +12 more
TL;DR: It is shown that intrinsic defects in tungsten disulphide play an important role in this proximity effect and that graphene can act as a probe to detect defects in semiconducting surfaces.
Journal ArticleDOI
Colossal enhancement of spin-orbit coupling in weakly hydrogenated graphene
Jayakumar Balakrishnan,Gavin Kok Wai Koon,Manu Jaiswal,Manu Jaiswal,A. H. Castro Neto,A. H. Castro Neto,Barbaros Özyilmaz +6 more
TL;DR: In this paper, it was shown that the controlled addition of small amounts of covalently bonded hydrogen atoms is sufficient to induce a colossal enhancement of the spin-orbit interaction by three orders of magnitude.
Journal ArticleDOI
Observation of long spin-relaxation times in bilayer graphene at room temperature.
Tsung-Yeh Yang,Jayakumar Balakrishnan,Frank Volmer,Ahmet Avsar,Manu Jaiswal,J. Samm,Syed Rizwan Ali,Alexandre Pachoud,Minggang Zeng,M. Popinciuc,Gernot Güntherodt,Bernd Beschoten,Barbaros Özyilmaz +12 more
TL;DR: The spin-relaxation time τ(s) scales inversely with the mobility μ of BLG samples both at room temperature (RT) and at low temperature (LT), indicating the importance of D'yakonov-Perel' spin scattering in BLG.
Journal ArticleDOI
Toward Wafer Scale Fabrication of Graphene Based Spin Valve Devices
Ahmet Avsar,Tsung-Yeh Yang,Sukang Bae,Jayakumar Balakrishnan,Frank Volmer,Manu Jaiswal,Zheng Yi,Zheng Yi,Syed Rizwan Ali,Gernot Güntherodt,Byung Hee Hong,Bernd Beschoten,Barbaros Özyilmaz +12 more
TL;DR: It is demonstrated that chemical vapor deposition specific structural differences such as nanoripples do not limit spin transport in the present samples, making Cu-CVD graphene a promising material of choice for large scale spintronic applications.
