A theoretical model for the calculation of the anisotropy in the electron Hall mobility is reported for n-type bulk single crystals of 4H-and 6H-SiC for the three distinct Hall measurement configurations: ͑a͒ ͓B ʈ c, jЌc], ͑b͒ ͓BЌc, jЌc], and ͑c͒ ͓BЌc, j ʈ c], where B, j, and c are the directions of the magnetic field, current flow, and c axis of the hexagonal unit cell, respectively. Comparison with experimental results shows that the anisotropy of the electron transport in both 4H-and 6H-SiC
more » ... both 4H-and 6H-SiC can be explained solely by the anisotropy in the effective electron mass tensors.
