Witryna2 mar 2024 · The 4H-SiC crystals were fabricated by using the generalized PVT method with three differently treated 3C-SiC powders (S1, S2, and S3) as starting materials. This PVT method has already been explained in detail by other researchers [ 16, 17 ]. Briefly, the 3C-SiC powder was placed at the bottom of the crucible in a PVT chamber.
