Abstract: Silicon carbide (SiC) has a large nuer of polytypes of which 3C-, 4H-, 6H-SiC are most common. Since different polytypes have different energy gaps and electrical properties, it is important to identify and characterize various SiC polytypes. Here

Characterization and modeling of the nitrogen passivation of interface traps in SiO Õ4H–SiC
6H and 15R–SiC.1,2 Scho¨rner et al.1 speculated that the poor mobility is caused by a large density of interface traps (Dit) beginning at ’3 eV from the valence band in all SiC polytypes.1 In 6H–SiC (E G53.02eV), most of these traps are loed in the conduction

Polytype transformations on the 4H-SiC(0001) Si face during top-seeded solution growth have been investigated by transmission electron microscopy and micro-Raman spectroscopy. 4H-, 15R-, and 6H-SiC were grown on the 4H-SiC(0001) Si face via spiral growth. Once a polytype transformation from 4H-SiC to 15R- or 6H-SiC occurs, the polytype rarely returns to 4H-SiC. Just before the polytype
