摘要: Abstract In this paper, properties of the Zn 1− X Be Se crystals grown from melt by high-pressure Bridgman method are reported. Spectroscopic ellipsometry has been used for determination complex dielectric function Se. On basis photon energy dependence function, gaps alloys containing different beryllium concentrations have evaluated. Measurements photoluminescence (PL) spectra allowed to find excitonic gap in investigated alloys. Auger electron spectroscopy (AES) with simultaneous argon ion sputtering surface composition. AES investigations make predictions concerning distribution particular elements samples.
