Webb1 maj 1987 · Abstract. The electrical properties of nitrogen-doped n -type 3C-SiC layers, epitaxially grown on Si by chemical vapor deposition, have been investigated at temperatures ranging from 10 to 1000 K. The activation energy of the N-donors was obtained from the temperature dependence of carrier density. The donor-density …
