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…
Conductance Distribution in Disordered Quantum Wires with a Perfectly Conducting Channel
Yositake Takane, Shingo Iwasaki, Yuka Yoshioka +2
We study the conductance of phase-coherent disordered quantum wires focusing on the case in which the number of conducting channels is imbalanced between two propagating directions…
Spin Injection and Detection in a Mesoscopic Superconductor at Low Temperatures
Yositake Takane
We theoretically study nonequilibrium spin transport in a superconducting wire connected by tunnel junctions to two ferromagnetic metal wires, each of which serves as an injector o…
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…
