Anomalous conduction band fluctuation in silicon carbide metal-oxide-semiconductor structures revealed by electrical characterization of field effect transistors combined with self-consistent numerical calculations
Koji Ito, Takuma Kobayashi, Tsunenobu Kimoto
We determined the interface state density () distributions in the vicinity of the conduction band edge in silicon carbide (SiC) metal-oxide-semiconductor (MOS) structur…
Influence of vacuum annealing on interface properties of SiC (0001) MOS structures
Koji Ito, Takuma Kobayashi, Tsunenobu Kimoto
We investigated the influence of vacuum annealing on interface properties of silicon carbide (SiC) metal-oxide-semiconductor (MOS) structures. For as-oxidized and nitric oxide (NO)…
Reduction of interface state density in SiC (0001) MOS structures by low-oxygen-partial-pressure annealing
Takuma Kobayashi, Keita Tachiki, Koji Ito +1
We report that annealing in low-oxygen-partial-pressure (low-p) ambient is effective in reducing the interface state density (D) at a SiC (0001)/SiO…
Carbon Ejection from a SiO2/SiC(0001) Interface by Annealing in High-Purity Ar
Takuma Kobayashi, Tsunenobu Kimoto
We found that carbon-associated byproducts formed at the dry-oxidized SiO2/SiC(0001) interface could be decomposed and be taken out to the SiO2 side by high-purity Ar annealing. We…
