Šiame baigiamajame magistro darbe nagrinėjamas alavo fosfido fotoelektroninis spektras. Tyrimo objektu pasirinktas Sn2P2S6 kristalas. Jis pasižymi pirmos rūšies faziniu virsmu. Kambario temperatūroje yra feroelektrikas, 360 K temperatūroje paraelektrikas. Darbe nagrinėjami kristalo fotoelektroninio spektro atlikto XPS metodu skitrumai po fazinio virsmo, bei atliktas lyginimas su teoriniu kristalo modeliu. Teorinis modelis remiasi Hartre-Foko-Rutano metodu. / In this graduating master`s work is researched photo electronis spectra of tin fosfydium crystal (Sn2P2S6). It is unique by ability to be feroelectric in ferophase (room temperature) and papaelectric in paraphase (360 K). In this work we are researching XPS differences of given crystal after the phasic transformation. Also we are comparing experimental XPS to theoretical crystal model, made by Hartree-Fock-Rutan method.
