Impurity defect definition
Witryna6 kwi 2024 · A natural SiC defect called the D I defect remains during the process, which may influence the properties of SiC. The most remarkable property of D I defects is that they can remain stable at 1700 °C and appear after various ions irradiation [ 1, 2, 3, 4, 5 ]. D I defects are also found in SiC layers grown on SiC substrates [ 6 ]. Witryna11 kwi 2024 · Impurities and structural defects such as dislocations lead to the deterioration of the characteristics of SCDs. For instance, nitrogen impurities reduce the mobilities of the charge carriers in SCDs drastically, while dislocation and dislocation bundles reduce SCDs’ strength and optical properties, respectively [ 2, 3, 4, 5 ].
