The linear and quadratic Zeeman effects have been studied for two different neutral-acceptor—bound-exciton complexes,(Ag, X) and (Cu, X), in high-purity p-type CdTe. For both complexes, the results are consistent with a bound-exciton ground state J= 1 2 in T d symmetry. The relevant electron g value is g e=− 1.77±0.02 for the electron, and K=+ 0.61±0.04 and L=− 0.04±0.02 for the hole parameters describing the isotropic and anisotropic Zeeman effects, respectively. The diamagnetic shift observed for the neutral-acceptor—bound-exciton complex is well explained in terms of the pseudodonor model.
