Single-crystal graphene on Ir(110)
Stefan Kraus, Felix Huttmann, Jeison Fischer +12
A single-crystal sheet of graphene is synthesized on the low-symmetry substrate Ir(110) by thermal decomposition of CH at 1500 K. Using scanning tunneling microscopy, low-e…
Contour integral method for obtaining the self-energy matrices of electrodes in electron transport calculations
Shigeru Iwase, Yasunori Futamura, Akira Imakura +3
We propose an efficient computational method for evaluating the self-energy matrices of electrodes to study ballistic electron transport properties in nanoscale systems. To reduce…
First-principles study on atomic configuration of electron-beam irradiated C clusters
Tomoya Ono, Shigeru Tsukamoto
A theoretical study proposes the atomic configuration of electron-beam irradiated C thin films. We examined the electronic structure and electron-transport properties of the…
Real-space electronic-structure calculations with full-potential all-electron precision for transition-metals
Tomoya Ono, Marcus Heide, Nicolae Atodiresei +3
We have developed an efficient computational scheme utilizing the real-space finite-difference formalism and the projector augmented-wave (PAW) method to perform precise first-prin…
Sudden Suppression of Electron-Transmission Peaks in Finite-Biased Nanowires
Shigeru Tsukamoto, Masakazu Aono, Kikuji Hirose
Negative differential conductance (NDC) is expected to be an essential property to realize fast switching in future electronic devices. We here present a thorough analysis on elect…
Electron-Transport Properties of Na Nanowires under Applied Bias Voltages
Shigeru Tsukamoto, Kikuji Hirose
We present first-principles calculations on electron transport through Na nanowires at finite bias voltages. The nanowire exhibits a nonlinear current-voltage characteristic and ne…
