  • Ab initio prediction of semiconductivity in a novel two-dimensional Sb2X3 (X= S, Se, Te) monolayers with orthorhombic structure 
    Bafekry, A.; Mortazavi, B.; Faraji, M.; Shahrokhi, M.; Shafique, A.; Jappor, H.R.; Nguyen, C.; Ghergherehchi, M.; Feghhi, S.A.H. (London : Nature Publishing Group, 2021)
    Sb 2S 3 and Sb 2Se 3 are well-known layered bulk structures with weak van der Waals interactions. In this work we explore the atomic lattice, dynamical stability, electronic and optical properties of Sb 2S 3, Sb 2Se 3 and ...
  • Electron transport through low-dimensional carbon-based systems 
    Slawig, Diana (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Carbon-based materials in all their facets yield an extremely large area of electronic applications. Its quasi-unlimited availability, wide ranging tuneability and scalability make them a potent rival to the currently ...
  • Photoconductivity of graphene devices induced by terahertz radiation at various photon energies 
    Salman, M.; Gouider, F.; Friedemann, M.; Schmidt, H.; Ahlers, Franz-J.; Göthlich, M.; Haug, Rolf J.; Nachtwei, G. (College Park, MD : American Institute of Physics, 2013)
    The influence of a magnetic field on Landau levels (LLs) in graphene-based devices is described via the magneto-optical response induced by terahertz (THz) radiation. For single-layer graphene, the resonance energies of ...
  • Quantum interference in an electron-hole graphene ring system 
    Smirnov, D.; Schmidt, H.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    Quantum interference is observed in a graphene ring system via the Aharonov Bohm effect. As graphene is a gapless semiconductor, this geometry allows to study the unique situation of quantum interference between electrons ...
  • Superlattice structures in twisted bilayers of folded graphene 
    Schmidt, Hennrik; Rode, Johannes C.; Smirnov, Dmitri; Haug, Rolf J. (London : Nature Publishing Group, 2014)
    The electronic properties of bilayer graphene strongly depend on relative orientation of the two atomic lattices. Whereas Bernal-stacked graphene is most commonly studied, a rotational mismatch between layers opens up a ...
  • Transport measurements on twisted graphene monolayers 
    Schmidt, H.; Lüdtke, T.; Barthold, P.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2011)
    Twisted graphene monolayers form a sample of two closely spaced two dimensional systems. We have performed transport measurements on such decoupled graphene layers being jointly contacted and conducting in parallel to ...
