    • Implementation of graphene multilayer electrodes in quantum dot light-emitting devices 

      Wolff, S.; Jansen, D.; Terlinden H.; Kelestemur, Y.; Mertin W.; Demir, Hilmi Volkan; Bacher G.; Nannen, E. (Springer Verlag, 2015)
      Graphene is a highly attractive candidate for implementation as electrodes in next-generation large-area optoelectronic devices thanks to its high electrical conductivity and high optical transparency. In this study, we ...
    • Surface evolution of 4H-SiC(0001) during in-situ surface preparation and its influence on graphene properties 

      Ul Hassan J.; Meyer, A.; Çakmakyapan, Semih; Kazar, Özgür; Flege J.I.; Falta J.; Özbay, Ekmel; Janzén, E. (Trans Tech Publications, Switzerland, 2013)
      The evolution of SiC surface morphology during graphene growth process has been studied through the comparison of substrate surface step structure after in-situ etching and graphene growth in vacuum. Influence of in-situ ...
    • Synthesis of graphene on ultra-smooth copper foils for large area flexible electronics 

      Polat, E. O.; Balcı, Osman; Kakenov, Nurbek; Kocabaş, Coşkun; Dahiya, R. (IEEE, 2015)
      This work demonstrates the synthesis of high quality, single layer graphene on commercially available ultra-smooth copper foils. The presented method will result in improved scalability of graphene based electronic and ...
    • Weighing graphene with QCM to monitor interfacial mass changes 

      Kakenov, N.; Balci, O.; Salihoglu, O.; Hur, S. H.; Balci, S.; Kocabas, C. (American Institute of Physics Inc., 2016)
      In this Letter, we experimentally determined the mass density of graphene using quartz crystal microbalance (QCM) as a mechanical resonator. We developed a transfer printing technique to integrate large area single-layer ...
