The B-exciton parameters in zinc oxide have been determined. The oscillator dependences in energy spectra of traps in cadmium tungsten have been detected. It has been shown that the B-serie lines in zinc diphosphide are associated with the states of pure spin magnetic-quadrupole orthoexciton. It has been proposed the phonon-roton dispersion law of quantum biexcitonic liquid in semiconductors; the dispersion curve parameters have been obtained; the spectrum of recombination emission of liquid has been calculated. The spectroscopic diagnostic of low dimension 2D-structures (stacking faults) in SiC has been carried out. T-excitons in carbazolecontaining polymers at Т=300К have been observed; their parameters have been determined. Product Description popup.authors popup.nrat_date 2020-04-02 Close
