Dephasing-Induced Stabilization of a Perfectly Conducting Channel in Disordered Graphene Nanoribbons with Zigzag Edges
Yuji Shimomura, Yositake Takane
Electron transport in a disordered graphene nanoribbon with zigzag edges is crucially affected by a perfectly conducting channel (PCC), which is stabilized if intervalley scatterin…
Electronic States and Local Density of States in Graphene with a Corner Edge Structure
Yuji Shimomura, Yositake Takane, Katsunori Wakabayashi
We study electronic states of semi-infinite graphene with a corner edge, focusing on the stability of edge localized states at zero energy. The 60°, 90°, 120° and 150° corner edges…
Hamiltonian decomposition for bulk and surface states
Ken-ichi Sasaki, Yuji Shimomura, Yositake Takane +1
We demonstrate that a tight-binding Hamiltonian with nearest- and next-nearest-neighbor hopping integrals can be decomposed into bulk and boundary parts in a general lattice system…
