Sic seed crystal
WebOur investigation requires stabilizing 4H-SIC crystal, which requires high carbon flux (low Si/C ratio), lower growth temperature and C-face of the 4H-SiC or 6H-SiC for its stability. So, we investigated the Si/C ratio in the PVT system for 4H-SIC SiC growth set up and found the temperature at which the Si/C ratio is close to unity or exactly ...

WebMar 4, 2011 · 6H-SiC single crystals have been successfully grown on (1015) plane seed by sublimation method. High density stacking faults (SFs) were observed by transmission synchrotron radiation X-ray topography. Based on the invisibility criteria of stacking faults, the displacement vectors of most SFs were determined to be the type of 1/6[1120].
