Essay

The thesis subject is investigations of the lattice dynamic characteristics and electronic energetic states of CuInSe2. Within the framework of the group-theory analysis using the method of complete groups, the selection rules in many-phonons processes of IR-absorbtion and Raman dissipation of light in such compounds, polarization effects and Jann-Teller effect are studied. Using MO-LCAO method in the cluster approximation qualitative changes in electronic spectrum, caused by change of In by impuritis of substitution Al and Ga are investigated. The system of equations which describes such renormalization of single atom potential into many component cluster is presented.
