Abstract

The effective g factor g^* of conduction electrons in degenerate CdTe has been determined by using measurements of the Cd¹¹³ nuclear spin-lattice relaxation time T₁ and the Knight shift K. It is shown that the magnitude of g^* is given by the Korringa product T₁TK²=C(g^*)², where C is a known constant and T is the absolute temperature, and that the sign of g^* is given by the sign of K for a spherically symmetric conduction band. The measured value, g^*=-1.1±0.1, is within the range allowed by effective-mass theory. Also, the electronic probability density at the nucleus, normalized to unity in an atomic volume, is calculated to be |ψ_F(0)|²≃6.5×10²⁵ cm^-3, about 70% of that found for the free Cd ion in a 5s²S_1/2 state.
