We have studied the D1 bound exciton (BE) in 3C-SiC (cubic) and 4H-SiC (hexagonal) by means of Zeeman spectroscopy. We show that the D-1-BE can be described by an electron-hole pair consisting of an (L-e = 0, S-e = 1/2) electron and a (L-h = 1, S-h = 1/2) hole, influenced by a number of interactions. In order to model the behaviour of the D-1-BE in magnetic field, an appropriate Hamiltonian equation is solved by using perturbation theory. The spin-orbit parameter and orbital g-value are small, indicating that the hole is tightly bound. (C) 1999 Elsevier Science B.V. All rights reserved.
