Charge Amounts of Doped Cr⁺(3d⁵, ⁶S) and Fe³⁺(3d⁵, ⁶S) Ions in II VI Compounds

Abstract

For the doped Cr⁺ and Fe³⁺ ions in the II VI compounds, the semiempirical relation derived previously (J. Phys. Soc. Jpn. 50 (1981) 1531) is applied which gives the number of electrons transferred to the empty orbits of the doped impurity ion. The obtained results describe successfully such physical situation that the excess charges of −e and +e are present at the impurity sites of the Cr⁺ and Fe³⁺ ions respectively.
