Intrinsic origin of electron scattering at 4H-SiC(0001)/SiO

Shigeru Iwase, Christopher James Kirkham, Tomoya Ono

We introduce a first-principles study to clarify the carrier-scattering property at the SiC/SiO. Interestingly, the electron transport at the conduction-band edge is significan…

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…
