O., Novosad S. S., Registration Date 21-01-2009 Organization Ivan Franko Lviv National University popup.description2 The phenomenon of a negative dispersion in gyrotropic paratellurite is predicted and conditions of its supervision are determined. The changes of energy-band structure, the mechanisms of the formation of space fieldcharge, the lifetime dependences of the charge carriersparameters versus ehe concentration of impurity-defect complexes in photorefractive CdTe semiconductor crystals doped by 3d-elements are established. The electronic states of optical and electroactive centers, thermo- and photostimulated recombinational and photochemical processes in lead,cadmium,calcium halides and lead, bismuth, itrium oxides crystals are investigated.
