  • About nanometer sized analogues of basic electronic and optical components 
    Quandt, Alexander; Özdoğan, Cem; Ferrari, Maurizio; Speranza, Giorgio (IEEE, 2008)
    We discuss a downsizing of optical components into the nanometer range. It presupposes the substitution of photons by ballistic electrons, but it also requires a simple and robust concept to assemble the analogues of basic ...
  • Boron doped graphene nanostructures 
    Quandt, Alexander; Özdoğan, Cem; Kuntsmann, Jens; Fehske, Holger (Wiley-Blackwell, 2008-10)
    We present results from an ab initio study of metallized semiconducting graphene nanostructures. Our model system consists of an alternating chain of quasi-planar B(7) clusters embedded into a semiconducting arm-chair ...
  • Feynman, biominerals and graphene - basic aspects of nanoscience 
    Quandt, Alexander; Özdoğan, Cem (Elsevier Science Bv, 2010-06)
    This article is about writing small. Inspired by R.P. Feynman's legendary talk There's plenty of room at the bottom, we recapitulate his famous Gedanken experiment of condensing a lot of useful information on the head of ...
  • Functionalizing graphene by embedded boron clusters 
    Quandt, Alexander; Özdoğan, Cem; Kunstmann, Jens; Fehske, Holger (IOP Publishing LTD, 2008-08-20)
    We present a model system that might serve as a blueprint for the controlled layout of graphene based nanodevices. The systems consists of chains of B-7 clusters implanted in a graphene matrix, where the boron clusters are ...
  • Stability of edge states and edge magnetism in graphene nanoribbons 
    Kuntsmann, Jens; Özdoğan, Cem; Quandt, Alexander; Fehske, Holger (Amer Physical Soc, 2011-01-21)
    We critically discuss the stability of edge states and edge magnetism in zigzag edge graphene nanoribbons (ZGNRs). We point out that magnetic edge states might not exist in real systems and show that there are at least ...
