Theory of the Stark Effect on the Donor Levels in 4H Silicon Carbide


Article Preview

The paper presents the results of a quantitative theoretical calculation concerning the shift and the splitting of the ground-state manifold of the nitrogen donor in 4H-SiC under uniform electric field. Two cases are distinguished corresponding to a field applied parallel and perpendicular to the crystal axis. A comparison with the phosphorus donor in Si is carried out.
