Structural analysis of polyaniline-polyprrole copolmers via pyrolysis mass spectrometry
Tezal, Feride; Küçükyavuz, Zuhal; Department of Chemistry (2007)
This thesis describes recent progress in electrochemical preparation of several conducting polymers. In particular, the synthesis and characterizations of pure polyaniline, pure polypyrrole, polyaniline/polypyrrole and polypyrrole/polyaniline copolymers and polyaniline-polypyrrole physical blends were studied. The focus has included firstly synthesis of these electrically conductive polymers. Secondly, thermal characteristics of electrochemically synthesized homopoly- mers, copolymers and their physical ble...
Structural characterization of intrinsic a-Si:H thin films for silicon heterojunction solar cells
Pehlivan, O.; Yilmaz, O.; Kodolbas, A. O.; Duygulu, O.; Tomak, Mehmet (2013-01-01)
We have utilized ex-situ spectroscopic ellipsometry and HRTEM to characterize the optical and structural properties of intrinsic a-Si:H thin layer that plays a key role for the improvement of the open circuit voltage in silicon heterojunction solar cells. Intrinsic a-Si:H films were deposited on (100) p-type CZ silicon wafers by using Plasma Enhanced Chemical Vapor Deposition (PECVD) technique at 225 degrees C substrate temperature and deposition time ranges from 15 s to 1800 s. Observed changes in the imag...
Structural characterization of polycrystalline Ag-In-Se thin films deposited by e-beam technique
Colakoglu, T.; Parlak, Mehmet (Elsevier BV, 2008-01-15)
The Ag-In-Se thin films were deposited by e-beam evaporation of the Ag3In5Se9 single crystal powder under high vacuum without intentional doping. Energy dispersive X-ray analysis (EDXA) showed the decreasing behavior of Se and Ag in the structure depending on the annealing. X-ray diffraction (XRD) analysis showed that as-grown films have amorphous structure while annealing the films under nitrogen environment at 200 degrees C transformed from the amorphous to polycrystalline structure. The crystallinity of ...

Pure and Mg(2+) & F(-) doped nano hydroxyapatites (HA) were synthesized by a precipitation method and sintered at 1100 degrees C to investigate their densification and structure. Different amounts of Mg(2+) and F ions were doped in to HAs. X-ray diffraction was used to identify the presence of phases And lattice parameters of HA and tri-calcium phosphates (TCP) present in the samples. Densification of HA was improved by the addition of these ions. In most of the doped samples, beta-tri-calcium phosphate (TC...
