Zeeman spectroscopy of shallow nitrogen donor in 3C-SiC

Zeeman spectra of the shallow nitrogen donor in 3C-SiC were investigated by infrared transmission measurements in different magnetic fields from B = 0 T up to 11 T in Faraday configuration (B\\k\\[1 1 1]). Based on the linear Zeeman splitting of the 2p(+/-) donor state, we deduce that the principal axes of effective mass ellipsoids in 3C-SiC lie along the [1 0 0] direction and the electron transverse effective mass m(t) = 0.241 +/- 0.004m(0), whi ch are in excellent agreement with the far infrared cyclotron resonance res ults. In addition, the nonlinear Zeeman shifts of the nitrogen donor states are also reported and discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
