Theoretical Study of Acceptor--Donor Complexes in 4H-SiC
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. WitrynaEffect of cerium impurity in the SiC source material on the 4H-SiC growth was investigated. 4H-SiC crystals were grown on 6H-SiC crystal seeds by physical vapor transport and using the open seed backside method. Cerium is the impurity used for promotion of the 4H polytype nucleation. The optimal amount of CeO 2 for the growth … Witryna1 gru 2024 · Schematic representations of the impurity locations are shown in Fig. 4.
