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…
Efficient calculation of the Green's function in scattering region for electron-transport simulations
Yoshiyuki Egami, Shigeru Tsukamoto, Tomoya Ono
We propose a first-principles method of efficiently evaluating electron-transport properties of very long systems. Implementing the recursive Green's function method and the shifte…
First-principles calculation method and its applications for two-dimensional materials
Yoshiyuki Egami, Shigeru Tsukamoto, Tomoya Ono
We present details of our effective computational methods based on the real-space finite-difference formalism to elucidate electronic and magnetic properties of the two-dimensional…
First-principles calculation method for electron transport based on grid Lippmann-Schwinger equation
Yoshiyuki Egami, Shigeru Iwase, Shigeru Tsukamoto +2
We develop a first-principles electron-transport simulator based on the Lippmann--Schwinger (LS) equation within the framework of the real-space finite-difference scheme. In our fu…
Spin relaxation in a zinc-blende (110) symmetric quantum well with delta-doping
Hiroshi Akera, Hidekatsu Suzuura, Yoshiyuki Egami
The spin relaxation of a two-dimensional electron system (2DES) formed in a symmetric quantum well is studied theoretically when the quantum well is parallel to the (110) plane of…
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…
