Local structural characteristics of Sb2Te3 films studied by reverse Monte Carlo modeling

Atomic configuration and connectivity of Sb2Te3 thin film are investigated using high-energy X-ray diffraction and reverse Monte Carlo simulation. Atomic model details of Sb2Te3 thin film are compared with liquid and amorphous Sb2Te3 reported in other article. Simulations show that both Sb–Sb and Te...

Zusammenfassung:Atomic configuration and connectivity of Sb2Te3 thin film are investigated using high-energy X-ray diffraction and reverse Monte Carlo simulation. Atomic model details of Sb2Te3 thin film are compared with liquid and amorphous Sb2Te3 reported in other article. Simulations show that both Sb–Sb and Te–Te homopolar bonds are present in the models. In phase transition process,atomic configuration of the sample rearranges gradually through the forming of Sb–Te bonds and the breaking of Sb–Sb and Te–Te bonds.
