| Vibronic coupling at a chromium ion in a trigonal field in GaAs (1983) | |||||||||||||||
Abstract | |||||||||||||||
| We present here the preliminary results of our calculations on the Cr 2+-X(0.839 eV lines) system in GaAs. These calculations show that it is necessary, in order to explain the zero field splitting, to introduce a strong trigonal field. The main points that are explained by the presence of a strong trigonal field are the reduction of the Jahn-Teller energy and the occurrence of vibronic lines labelled I and J. A spin Hamiltonian is also presented that explains the zero field fine structure and the line intensities. | |||||||||||||||
