Abstract(in Japanese) (See Japanese page)
Abstract(in English) Density functional theory calculations for investigation of electronic structure and charrier scattering property of the 4H-SiC(0001)/SiO2 interface with atomic scale steps are performed. We find that the bonding structure with SiO2 affects the electronic structure of the 4H-SiC(0001)/SiO2 interface. Carrier scattering property calculation reveals that two conduction channels contribute the electron conduction at the interface. The behavior of the electrons flowing inside the substrate is insensitive to the existence of the step edges while that of the electrons flowing the channel immediately below the interface is affected at the step edge, resulting in the reduction of the transmission.
