    • 2D vibrational properties of epitaxial silicene on Ag(111) 

      Solonenko, D.; Gordan, O. D.; Lay, G. L.; Sahin, H.; Cahangirov, S.; Zahn, D. R. T.; Vogt, P. (IOP Publishing, 2016-10)
      The two-dimensional silicon allotrope, silicene, could spur the development of new and original concepts in Si-based nanotechnology. Up to now silicene can only be epitaxially synthesized on a supporting substrate such as ...

    • Anisotropic electronic, mechanical, and optical properties of monolayer WTe2 

      Torun, E.; Sahin, H.; Cahangirov, S.; Rubio, A.; Peeters, F. M. (American Institute of Physics Inc., 2016)
      Using first-principles calculations, we investigate the electronic, mechanical, and optical properties of monolayer WTe2. Atomic structure and ground state properties of monolayer WTe2 (Td phase) are anisotropic which are ...

    • Bilayer SnS2: tunable stacking sequence by charging and loading pressure 

      Bacaksiz, C.; Cahangirov, S.; Rubio, A.; Senger, R. T.; Peeters, F. M.; Sahin, H. (American Physical Society, 2016-03)
      Employing density functional theory-based methods, we investigate monolayer and bilayer structures of hexagonal SnS2, which is a recently synthesized monolayer metal dichalcogenide. Comparison of the 1H and 1T phases of ...

    • Debris removal during disaster response: a case for Turkey 

      Sahin, H.; Kara, B. Y.; Karasan, O. E. (Elsevier, 2016)
      Debris occurs from the ruin and wreckage of structures during a disaster. Proper removal of debris is of great importance because it blocks roads and prohibits emergency aid teams from accessing disaster-affected regions. ...

    • Frictional figures of merit for single layered nanostructures 

      Cahangirov, S.; Ataca, C.; Topsakal, M.; Sahin, H.; Çıracı, Salim (American Physical Society, 2012)
      We determine the frictional figures of merit for a pair of layered honeycomb nanostructures, such as graphane, fluorographene, MoS 2 and WO 2 moving over each other, by carrying out ab initio calculations of interlayer ...

    • Hydrogen-induced sp2-sp3 rehybridization in epitaxial silicene 

      Solonenko, D.; Dzhagan, V.; Cahangirov, S.; Bacaksiz, C.; Sahin, H.; Zahn, D. R. T.; Vogt, P. (American Physical Society, 2017)
      We report on the hydrogenation of (3×3)/(4×4) silicene epitaxially grown on Ag(111) studied by in situ Raman spectroscopy and state-of-the-art ab initio calculations. Our results demonstrate that hydrogenation of (3×3)/(4×4) ...

    • Monolayers of MoS2 as an oxidation protective nanocoating material 

      Sen, H. S.; Sahin, H.; Peeters, F. M.; Durgun, Engin (AIP Publishing, 2014-08-26)
      First-principle calculations are employed to investigate the interaction of oxygen with ideal and defective MoS2 monolayers. Our calculations show that while oxygen atoms are strongly bound on top of sulfur atoms, the ...

    • Realization of a p-n junction in a single layer boron-phosphide 

      Çakır, D.; Kecik, D.; Sahin, H.; Durgun, Engin; Peeters, F. M. (Royal Society of Chemistry, 2015)
      Two-dimensional (2D) materials have attracted growing interest due to their potential use in the next generation of nanoelectronic and optoelectronic applications. On the basis of first-principles calculations based on ...
