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. Witryna3 gru 2024 · The 4H-SiC crystal ingot was grown on (000-1) face of 4H-SiC seed, in a mixed atmosphere of argon and nitrogen, at an atmosphere pressure of 16 Torr, with high purity boron carbide and SiC powder in the graphite crucible, at a monitoring temperature range from 2030 °C to 2100 °C for 80 hours.
WitrynaImprovements in purity of the growth environment and in the growth process has resulted in yield improvements from 10-25% to 70-85% of high resistivity (> 5000 ohm-cm) 4H-SiC crystal and is attributed to the improvements in the source and growth environment purity. 3.
