Junction properties between conducting polymer composites of polypyrrole/polyindene (PPy/PIn) with different conductivities and metals like Pt, Au, Al and In have been investigated. Rectifying junctions were observed for low work function metals, In and Al; however, high work function metals, Pt and Au, were observed to form ohmic contacts to PPy/PIn composite in the sandwich geometry. The rectifying behavior of the metal/composite/Pt junctions improved when the conductivity of the composite was decreased from I to 0.01 S/cm. Using the ideal Schottky theory various junction parameters have been determined. Ail planar junctions were ohmic regardless of the conductivities of the samples.

Interfacial reaction kinetics and microstructural evolution of C/SiC composites to metal joints Saltık, Simge; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2021-9-09) In the present study, joining of two dissimilar materials namely C/SiC composites and Ti6Al4V alloys by brazing using Ag-Cu based brazing filler alloys have been investigated. The effect of active Ti element content, additive particle size/amount in the filler alloy together with the reinforcement structure, material properties of the C/SiC composite on the interface evolution mechanism and resulting mechanical performance of the brazed joints have been examined. Additionally, apart from the brazing studies...
Electrical transport, optical and thermal properties of polyaniline-pumice composites YILMAZ, KORAY; Akgoz, A.; Cabuk, M.; Karaagac, H.; KARABULUT, ORHAN; YAVUZ, Mustafa (2011-11-01) In this study, electrical conductivity, photoconductivity, absorbance and thermal properties of polyaniline (PANI) and polyaniline-pumice composites were investigated. Temperature dependent conductivity and photoconductivity measurements were carried out in the temperature range of 80-400K. The measurements revealed that the dominant conduction mechanisms in polyaniline and 15% pumice doped composite were hopping conduction. The low activation energies calculated for 36% pumice doped composite indicated tha...
Electronic properties of transition metal oxides Mete, Ersen; Ellialtıoğlu, Süleyman Şinasi; Department of Physics (2003) Transition metal oxides constitute a large class of materials with variety of very interesting properties and important technological utility. A subset with perovskite structure has been the subject matter of the current theoretical investigation with an emphasis on their electronic and structural behavior. An analytical and a computational method are used to calculate physical entities like lattice parameters, bulk moduli, band structures, density of electronic states and charge density distributions for v...
Thermal degradation of polythiophene-natural rubber and polythiophene-synthetic rubber conducting polymer composites Hacaloğlu, Jale; Akbulut, Ural; Toppare, Levent Kamil (1997-01-01) Thermal degradation of conducting polymer composites of polythiophene and rubbers was studied by direct and indirect pyrolysis mass spectrometry techniques. The samples were prepared by electrooxidation of polythiophene using natural rubber or synthetic rubber as the insulating matrix. Presence of decomposition products which were not observed during pyrolysis of pure polythiophene and rubbers, and disappearance of rubber-based pyrolysis mass peaks, together with changes in thermal stability and behaviour, ...
Nanocrystallization in Cu-Zr-Al-Sm Bulk Metallic Glasses Sıkan, Fatih; Yaşar, Bengisu; KALAY, İLKAY (Springer Science and Business Media LLC, 2018-04-01) The effect of rare-earth element (Sm) microalloying on the thermal stability and crystallization kinetics of melt-spun ribbons and suction-cast rods of Zr48Cu38.4Al9.6Sm4 alloy were investigated using differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM), and atom probe tomography (APT). The XRD results of constant heating rate annealing indicated that amorphous Zr48Cu38.4Al9.6Sm4 melt-spun ribbons devitrifies into Cu2Sm at 673 K (400 A degrees C). The sequ...
