Impurity's 4h
Witryna2 mar 2024 · The growth of the 4H-SiC crystals took place at a growth temperature in the range of 1900–2100 °C and a pressure of 10 −2 to 10 −3 mbar in an argon atmosphere. The grown crystal sample was detached from the crucible and ground to two-inch diameter by slicing and then polishing to prepare the SiC wafers.
