First-principles study on structure and anisotropy of high N-atom density layer in 4H-SiC
Mitsuharu Uemoto, Naoki Komatsu, Yoshiyuki Egami +1
A nitridation annealing process is well employed to reduce interface trap states that degrade the channel mobility of 4H-SiC/SiO metal-oxide-semiconductor field-effect transi…
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…
Fully spin-dependent transport of triangular graphene flakes
Tomoya Ono, Tadashi Ota, Yoshiyuki Egami
The magnetic moment and spin-polarized electron transport properties of triangular graphene flakes surrounded by boron nitride sheets (BNC structures) are studied by using first-pr…
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 Study on Electron Conduction in Sodium Nanowire
Y. Egami, T. Sasaki, T. Ono +1
We present detailed first-principles calculations of the electron-conduction properties of a three-sodium-atom nanowire suspended between semi-infinite crystalline Na(001) electrod…
Even-Odd Oscillation in Conductance of Single-Row Sodium Nanowire
Y. Egami, T. Ono, K. Hirose
We present a first-principles calculation of the electronic conduction properties of single-row sodium nanowires suspended between semi-infinite electrodes. The conductance of the…
