In this study three different organic semiconductors were used in the fabrication of ITO/ PEDOT:PSS/Polymer:PCBM/LiF/Al configuration. Reverse current density-voltage (J(r)-V) measurements of the samples were investigated to define the reverse-bias leakage current mechanisms on benzotriazole and benzothiadiazole based organic devices. Our results indicate that the J(r)-V plot behaviors are given by linear dependence between In (J(r)) and V-1/(2), where J(r) is the reverse current density, and V is the applied voltage. This behavior is well known as the Poole-Frenkel (PF) effect where it is found to be dominating in the reverse-bias leakage current.

Poly(lactic acid) based nanocomposites: mechanical, thermal and rheological properties and morphology Açık, Eda; Yılmazer, Ülkü; Department of Chemical Engineering (2014) The aim of this study was to increase the potential applications of poly(lactic acid) (PLA) by incorporating reactive functionalities with different nano-scale fillers. To investigate the effects of nanoclay types, five different organically modified nanoclays (Cloisites®15A, 25A and 30B and Nanofils®5 and 8) were used. Two elastomeric compatibilizers, ethylene-glycidyl methacrylate (E-GMA) and ethylene-butyl acrylate-maleic anhydride (E-BA-MAH), were added to the nanocomposites produced via melt compoundin...
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...
Energy transfer and stimulated emission dynamics at 1.1 mu m in Nd-doped SiNx Li, Rui; Yerci, Selçuk; Kucheyev, Sergei O.; van Buuren, Tony; Dal Negro, Luca (2011-03-14) Neodymium (Nd) doped amorphous silicon nitride films with various Si concentrations (Nd:SiNx) were fabricated by reactive magnetron co-sputtering followed by thermal annealing. The time dynamics of the energy transfer in Nd:SiNx was investigated, a systematic optimization of its 1.1 mu m emission was performed, and the Nd excitation cross section in SiNx was measured. An active Nd:SiNx micro-disk resonator was fabricated and enhanced radiation rate at 1.1 mu m was demonstrated due to stimulated emission at ...
Poly(lactic acid) blends, composites and fibers and direct pyrolysis mass spectrometry for nanoclay composites Özdemir, Esra; Hacaloğlu, Jale; Kayran İşçi, Ceyhan; Department of Polymer Science and Technology (2017) In the first part of this study, poly(lactic acid)-poly(ethylene glycol), PLA-PEG, blends, composites and electrospun fibers of PLA and PLA composites, PLA-PEG blends and PLA-PEG, blends composites were prepared and characterized. X-ray Diffractometer (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Gel Permeation Chromatography (GPC), Simultaneous Thermal Analyzer (STA) and Direct Pyrolysis Mass Spectrometer (DP-MS) techniques were used for characterization studies. Both T...
Sorption of BB41 dye molecules using chitosan based particles from aqueous solutions: A kinetic and thermodynamic evaluation Demirtas, Hulya; Tasar, Seyda; Kaya, Fatih; Ozer, Ahmet (2022-08-01) In this study, starting from chitosan is a hydrophilic polymer with positively charged, it was aimed to produce chitosan-based particles and to be evaluated as a sorbent. Chitosan-based polymeric particles production was carried out by the precipitation-collection method from chitosan. Chitosan and chitosan-based sorbent were characterized. For this purpose, SEM and FTIR analyzes were used. Sorption activities of the chitosan-based polymeric particles were investigated for basic dye (basic blue 41, BB41). T...
