First-principles transport calculation method based on real-space finite-difference nonequilibrium Green's function scheme
Tomoya Ono, Yoshiyuki Egami, Kikuji Hirose
We demonstrate an efficient nonequilibrium Green's function transport calculation procedure based on the real-space finite-difference method. The direct inversion of matrices for o…
Novel time-saving first-principles calculation method for electron-transport properties
Yoshiyuki Egami, Kikuji Hirose, Tomoya Ono
We present a time-saving simulator within the framework of the density functional theory to calculate the transport properties of electrons through nanostructures suspended between…
First-principles calculation of electronic polarization of III-V nanotubes
Jun Otsuka, Tomoya Ono, Kikuji Hirose
A first-principles study of the electronic polarization of BN and AlN nanotubes and their graphitic sheets under an external electric field has been performed. We found that the po…
First-Principles Study on Electron-Conduction Properties of C Chains
Tomoya Ono, Kikuji Hirose
The electron-conduction properties of fullerene chains are examined by first-principles calculations based on the density functional theory. The conductivity of the C dimer…
First-principles study of tunnel current between scanning tunneling microscopy tip and hydrogen-adsorbed Si(001) surface
Tomoya Ono, Shinya Horie, Katsuyoshi Endo +1
A scanning tunneling microscopy (STM) image of a hydrogen-adsorbed Si(001) surface is studied using first-principles electron-conduction calculation. The resultant STM image and sc…
First-principles study on scanning tunneling microscopy images of hydrogen-terminated Si(110) surfaces
Shinya Horie, Kenta Arima, Kikuji Hirose +3
Scanning tunneling microscopy images of hydrogen-terminated Si(110) surfaces are studied using first-principles calculations. Our results show that the calculated filled-state imag…
