Control of electric current by graphene edge structure engineering
Masayuki Yamamoto, Katsunori Wakabayashi
In graphene nanoribbon junctions, the nearly perfect transmission occurs in some junctions while the zero conductance dips due to anti-resonance appear in others. We have classifie…
Electronic transport properties of graphene nanoribbons
Katsunori Wakabayashi, Yositake Takane, Masayuki Yamamoto +1
We will present brief overview on the electronic and transport properties of graphene nanoribbons focusing on the effect of edge shapes and impurity scattering. The low-energy elec…
Nearly Perfect Single-Channel Conduction in Disordered Armchair Nanoribbons
Masayuki Yamamoto, Yositake Takane, Katsunori Wakabayashi
The low-energy spectrum of graphene nanoribbons with armchair edges (armchair nanoribbons) is described as the superposition of two non-equivalent Dirac points of graphene. In spit…
Edge Effect on Electronic Transport Properties of Graphene Nanoribbons and Presence of Perfectly Conducting Channel
Katsunori Wakabayashi, Yositake Takane, Masayuki Yamamoto +1
Numerical calculations have been performed to elucidate unconventional electronic transport properties in disordered nanographene ribbons with zigzag edges (zigzag ribbons). The en…
