Density functional theory study on effect of NO annealing for SiC(0001) surface with atomic-scale steps
Mitsuharu Uemoto, Nahoto Funaki, Kazuma Yokota +2
Density functional theory calculations for the electronic structures of the 4H-SiC(0001)/SiO interface with atomic-scale steps are carried out to investigate the effect of NO a…
Density functional theory calculations for investigation of atomic structures of 4H-SiC/SiO interface after NO annealing
Naoki Komatsu, Mizuho Ohmoto, Mitsuharu Uemoto +1
We propose the atomic structures of the 4H-SiC/SiO interface for the , , C, and Si faces after NO annealing. Our proposed structures preferentially form at the topmost la…
Theoretical investigation of vacancy related defects at 4H-SiC(000)/SiO interface after wet oxidation
Mukai Tsunasaki, Tomoya Ono, Mitsuharu Uemoto
The stability and formation mechanism of the defects relevant to silicon and carbon vacancies at the 4H-SiC(000)/SiO interface after wet oxidation are investigated by…
Density functional study of twisted graphene -FePd heterogeneous interface
Mitsuharu Uemoto, Hayato Adachi, Hiroshi Naganuma +1
Graphene on -FePd(001), which has been experimentally studied in recent years, is a heterogeneous interface with a significant lattice symmetry mismatch between the honeycomb…
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 and Scalable Calculation of Complex Band Structure using Sakurai-Sugiura Method
Shigeru Iwase, Yasunori Futamura, Akira Imakura +2
Complex band structures (CBSs) are useful to characterize the static and dynamical electronic properties of materials. Despite the intensive developments, the first-principles calc…
