Times Cited Count:7 Percentile:94.47(Materials Science, Multidisciplinary)Metal-Oxide (SiO)-Semiconductor (MOS) structures fabricated on Silicon Carbide (SiC) were studied using Electrically Detected Magnetic Resonance technique (EDMR). The residual Carbons are expected to be near the interface between SiC and SiC-SiO
SiO
, which is different from Si-SiO
interface. By the EDMR measurements at 50K, a defect center related to C dangling bonds which is called P
center and also a center related to C dangling bonds terminated by hydrogens or nitrogens (Ns) which is called P
were observed. In addition, a center related to N donor which is called Nh exist near the interface from N-treatment samples. This suggests that carrier concentration increases near the interface due to the introduction of donors, and as a result, the channel conductance increases.
