摘要
As there is strong covalence in III-V semiconductors, the effect of the difference between the t(2g) orbit and e(g) orbit must be considered in their electric structure. In this paper we present a modified Sugano-Tanabe scheme and give the energy matrix of the d(2) system and the g-factor formula of (3)A(2) ground state including different covalency. Using the matrix and the g-factor formula, we have calculated the optical spectra and the gyromagnetic factor of V3+ in GaAs, GaP and InP with the T-d system. The calculated results agree with experimental findings. (C) 2000 Elsevier Science B.V. All rights reserved.
