Abstract

U ovoj doktorskoj disertaciji detaljno su izuĉavane optiĉke osobine nanodimenzionih sistema formiranih u tri razliĉita materijala: plastiĉno deformisanom bakru, tankim filmovima CdS i heterostrukturama CdTe/ZnTe. Optiĉke osobine plastiĉno deformisanog bakra ispitivane su tehnikama spektroskopske elipsometrije i Ramanove spektroskopije, dok je površina uzorka ispitivana mikroskopijom atomske sile. Optiĉke osobine tankih filmova CdS razliĉite debljine ispitivane su metodama daleke infracrvene spektroskopije i Ramanove spektroskopije, a površina uzorka ispitivana je mikroskopijom atomske sile. Optiĉke osobine heterostruktura CdTe/ZnTe ispitivane su metodama fotoluminescencije, Ramanove spektroskopije i daleke infracrvene spektroskopije.

: In this PhD thesis the optical properties of nanoscaled systems developed in three different systems are thoroughly studied. The optical properties of plastically deformed copper are investigated by means of spectroscopic ellipsometry and Raman spectroscopy, and the samples surface was investigated by AFM measurements. Optical properties of CdS thin films of different thickness were investigated by means of Raman spectroscopy and far - infrared spectroscopy, and the surface of the samples was studied with AFM measurements. And finally, optical properties of CdTe/ZnTe heterostructures were investigated with photoluminescence, Raman spectroscopy and far - infrared spectroscopy.
