| dc.description.abstract | The amorphous structure of (Ga2Se3)0.25(GeSe2)0.75 is investigated using a combination of anomalous X-ray scattering (AXS) and Reverse-Monte-Carlo (RMC) modeling. It was confirmed that the Ga and Ge atoms can be found exclusively in the tetrahedral configuration. The average coordination number of the Se atoms is found to be 2.34(3) due to the presence of dative bonds. The formation of Ga/Ge-Ga/Ge so-called “wrong bonds” is discussed based on a set of RMC simulations. A strong Ga-Ga second neighbor correlations indicates the formation of Ga-Se clusters within the Ga-Ge-Se glass. | eng |
| dc.description.abstract-translated | Amorfní struktura (Ga2Se3)0.25(GeSe2)0.75 je zkoumána kombinací anomalního rentgenového rozptylu (AXS) a modelováním pomocí reverzního Monte-Carla (RMC). Bylo potvrzeno, že Ga a Ge atomy existují exkluzivně v tetraedrické konfiguraci. Průměrné koordinační číslo atomů Se je 2.34(3) kvůli přítomnosti dativních vazeb. Tvorba Ga/Ge-Ga/Ge takzvaných „homopolárních vazeb“ je diskutována pomocí RMC simulací. Silná korelace Ga-Ga v druhé koordinační sféře naznačuje tvorbu Ga-Se klastrů uvnitř Ga-Ge-Se skla. | cze |
