WitrynaElemental impurities can substantially impact the optical and transport properties of semiconductors and their performance in devices.Impurity incorporation is strongly governed by the synthesis conditions, and prior to the start of the project, BASiC-3C identified impurities as a potential source of nonideal behavior in their SiC material. WitrynaHall-effect, ESR, and SIMS measurements were carried out for these 3C-SiC epilayers. The epilayers having carrier densities below l×l0 15 cm-3 showed no significant 3-line ESR signal associated with nitrogen impurities. The reduction in residual carrier density is explained in terms of the nitrogen impurity concentration in 3C-SiC epilayers.
