Popis: | 4H-SiC MOS capacitors were used to characterize the effect of reactive-ion etching of the SiC surface on the electrical properties of N2O-grown thermal oxides. The oxide breakdown field reduces from 9.5 MV/cm with wet etching to saturate at 9.0 MV/cm with 30% reactive-ion over-etching. Additionally, the conduction-band offset barrier height, φB, progressively decreases from 2.51 eV with wet etching to 2.46 eV with 45% reactive-ion over-etching. |
