Probing a divergent van Hove singularity of graphene with a CaN support: a layered electride as a solid-state dopant
Takeshi Inoshita, Masaru Tsukada, Susumu Saito +1
Layered electrides, as typified by CaN, are a new class of quasi-two-dimensional materials with low work functions. Using first-principles calculations, we have shown that a gr…
Scanning tunneling microscopy and spectroscopy of the electronic local density of states of graphite surfaces near monoatomic step edges
Y. Niimi, T. Matsui, H. Kambara +3
We measured the electronic local density of states (LDOS) of graphite surfaces near monoatomic step edges, which consist of either the zigzag or armchair edge, with the scanning tu…
STS Observations of Landau Levels at Graphite Surfaces
T. Matsui, H. Kambara, Y. Niimi +3
Scanning tunneling spectroscopy measurements were made on surfaces of two different kinds of graphite samples, Kish graphite and highly oriented pyrolytic graphite (HOPG), at very…
Efficient method for simulating quantum electron dynamics under the time dependent Kohn-Sham equation
Naoki Watanabe, Masaru Tsukada
A numerical scheme for solving the time-evolution of wave functions under the time dependent Kohn-Sham equation has been developed. Since the effective Hamiltonian depends on the w…
Finite element approach for simulating quantum electron dynamics in a magnetic field
Naoki Watanabe, Masaru Tsukada
A fast and stable numerical method is formulated to compute the time evolution of a wave function in a magnetic field by solving the time-dependent Schroedinger equation. This comp…
Relation between the transmission rates and the wave functions in the carbon nanotube junctions
Ryo Tamura, Masaru Tsukada
Electron transmission and wave functions through junctions with a pair of a pentagonal defect and a heptagonal defect connecting two metallic carbon nanotubes are analyzed by the a…
