Main research interests
  • transport properties of mesoscopic systems, metal-, superconductor- and ferromagnetic hybrid systems, spectra of Andreev billiards
  • DFT and Huckel calculations on carbon based nanosctructures (graphene, nanotubes, fullerene-cubance co-crystals, etc)
  • Raman spectra simulation of novel two dimensional materials (silicene, germanene, MoS2, BiTeI, etc)
