Description

By diagonalizing the complete energy matrix of a d4 configuration ion in tetragonal symmetry, the zero-field-splitting parameters a, D and F of InP:Cr2+ have been studied. The local structure distortion parameters ΔR=0.08 A and Δθ=1.01 were estimated. They show an expansion distortion around Cr2+ in the InP semiconductor. The Jahn-Teller energy EJT is found to be about 413 cm-1, which agrees well with the experiment. - PACS numbers: 75.10.Dg; 76.30.-v (orig.)
