Öğe Modelling study of liquid chalcogenide of Se20Te80 alloy depending on temperature(Natl Inst Optoelectronics, 2009) Dalgic, S.; Yavuz, S. S.; Colakogullari, M.The structural properties of the liquid chalcogenicle of Se20Te80 alloy have been calculated using Reverse Monte Carlo (RMC) modelling technique at three thermodynamic states which are at 420 degrees C, 530 degrees C and 650 degrees C. The quality of models has been improved using fitting procedure to neutron diffraction data. The atomic configurations and bond angle distributions of these systems have been calculated. The static structural functions of the liquid chalcogenide alloy belong to the resulting model where used plausible constraints have been compared with available experimental values. Finally, the obtained results correspond to related thermodynamic states show that the RMC modelling technique can be used to product three-dimensional atomic configurations.Öğe THE STRUCTURAL AND ELECTRONIC PROPERTIES OF n-POLYPYRROLE/ HOLLOW GOLD MONOLAYER HYBRID NANOSTRUCTURES BY AB-INITIO SIMULATIONS(Virtual Inst Physics, 2019) Dalgic, S. S.; Yavuz, S. S.; Dalgic, S.; Kandemirli, F.In this work, we have investigated the new generation hybrid nanostmctures combined with n-Polypyrolle monomer and hollow Au monolayer surfaces by ab-inito simulation method. Interfacial interactions between n-PPy monomer and the hollow FCC Au monolayer surfaces have obtained by density functional calculations (DFT) using the GAUSSIAN 09 program package. We have considered the one and two monomer of PPy located at inner part of hollow monolayer of gold (100) surfaces. Optimized geometry, Quantum chemical calculations of hybrid nanostmctures have obtained. The results show that the interface energy increases the number of PPy monomer increases. And depends on the position of the n-PPy deposited in the hollow Au (100) monolayer. It has found that the electron transfers from n-PPy to monolayer surface of the hybrid structure.
