Electron Wave Function in Armchair Graphene Nanoribbons
K. Sasaki, K. Wakabayashi, T. Enoki
By using analytical solution of a tight-binding model for armchair nanoribbons, it is confirmed that the solution represents the standing wave formed by intervalley scattering and…
Polarization Dependence of Raman Spectra in Strained Graphene
K. Sasaki, K. Wakabayashi, T. Enoki
The polarization dependences of the G, D, and 2D (G) bands in Raman spectra at graphene bulk and edge are examined theoretically. The 2D and D bands have different selection rul…
Soliton Trap in Strained Graphene Nanoribbons
Ken-ichi Sasaki, Riichiro Saito, Mildred S. Dresselhaus +2
The wavefunction of a massless fermion consists of two chiralities, left-handed and right-handed, which are eigenstates of the chiral operator. The theory of weak interactions of e…
Chiral Gauge Theory for Graphene Edge
Ken-ichi Sasaki, Katsunori Wakabayashi
An effective-mass theory with a deformation-induced (an axial) gauge field is proposed as a theoretical framework to study graphene edge. Though the gauge field is singular at edge…
Berry's Phase for Standing Wave Near Graphene Edge
Ken-ichi Sasaki, Katsunori Wakabayashi, Toshiaki Enoki
Standing waves near the zigzag and armchair edges, and their Berry's phases are investigated. It is suggested that the Berry's phase for the standing wave near the zigzag edge is t…
