The Hall stering coefficient rH determines the relationship between the measurable Hall coefficient RH and the free carrier concentration. Reliable knowledge of rH is necessary for the precise interpretation of Hall measurements and to validate theoretical transport calculations. We have measured the Hall stering factor in nitrogen doped 4H and 6H

1995/7/15· The band structures of 6H SiC and 4H SiC calculated by means of the full-potential linear-muffin-tin-orbital method are used to determine the effective mass tensors for their conduction-band minima. The results are shown to be consistent with recent optically detected cyclotron resonance measurements, which find the ratio of cyclotron masses for B ⊥ c to B ∥ c to be larger (smaller) than
