20.500.12556/DKUM-67641 Specific EXAFS tools in analysis of MoSI nanowires The structure of nanowires prepared by vapor synthesis from Mo, S and I is investigated by methods of x-ray diffraction (XRD) and extended x-ray absorption fine structure (EXAFS). Starting with a qualitative model of the structure from XRD, the metrics is introduced with interatomic distances determined from EXAFS. Two specific tools to increase the resolution of EXAFS method are discussed: the reciprocity relation between data from adjacent target atoms, and difference EXAFS from data on samples with small changes in stoichiometry. Z metodama rentgenske difrakcije (XRD) in podaljšane strukture rentgenskih absorpcijskih robov (EXAFS) smo raziskali strukturo nanožičk, dobljenih s sintezo par elementov Mo, S in I. V kvalitativni model strukture, postavljen na osnovi difrakcijske slike, uvedemo metriko s pomočjo medatomskih razdalj, ugotovljenih z metodo EXAFS. Podrobneje bomo obravnavali dve posebni orodji, s katerima izboljšamo ločljivost metode EXAFS: recipročne povezave, ki veljajo za prispevke sosednjih atomov v vzorcu, in diferenčni EXAFS za podatke iz vzorcev z majhnimi spremembami v stehiometriji.
