We report on the fabrication and performance of vacuum-processed organic field effect transistors utilizing evaporated low-density polyethylene (LD-PE) as a dielectric layer. With C-60 as the organic semiconductor, we demonstrate low operating voltage transistors with field effect mobilities in excess of 4 cm(2)/Vs. Devices with pentacene showed a mobility of 0.16 cm(2)/Vs. Devices using tyrian Purple as semiconductor show low-voltage ambipolar operation with equal electron and hole mobilities of similar to 0.3 cm(2)/Vs. These devices demonstrate low hysteresis and operational stability over at least several months. Grazing-angle infrared spectroscopy of evaporated thin films shows that the structure of the polyethylene is similar to solution-cast films. We report also on the morphological and dielectric properties of these films. Our experiments demonstrate that polyethylene is a stable dielectric supporting both hole and electron channels.

Ternary nanocomposites of low density, high density and linear low density polyethylenes with the compatibilizers E-MA-GMA and E-BA-MAh Işık Coşkunses, Fatma; Yılmazer, Ülkü; Department of Chemical Engineering (2011) The effects of polyethylene, (PE), type, compatibilizer type and organoclay type on the morphology, rheological, thermal, and mechanical properties of ternary low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE), matrix nanocomposites were investigated in this study. Ethylene – Methyl acrylate – Glycidyl methacrylate terpolymer (E-MAGMA) and Ethylene – Butyl acrylate- Maleic anhydrate terpolymer (E-BA-MAH) were used as the compatibilizers. The organo...
Photoconductivity of P3HT films measured by time-resolved THz spectroscopy Esentürk, Okan; Heilweil, Edwin J. (Optical Society of America (OSA); 2007-01-01) Photoconductivities of P3HT polymer films varying in molecular weight were directly measured and compared using optical pump-THz probe spectroscopy. Conductivities of P3HT polymers depend on the polymer length, ring orientation regularity and film morphology. © 2007 Optical Society of America.
Nanocomposites based on blends of polyethylene Işık, Fatma; Yılmazer, Ülkü; Department of Chemical Engineering (2005) In this study the effects of compatibilizer type, organoclay type, and the addition order of components on the morphological, thermal, mechanical and flow properties of ternary nanocomposites based on low density polyethylene, LDPE were investigated. As compatibilizer, ethylene/methyl acrylate/glycidyl methacrylate, ethylene/glycidyl methacrylate, and ethylene/butyl acrylate/maleic anhydride; as organoclay Cloisite? 15A, Cloisite? 25A and Cloisite? 30B were used. All samples were prepared by a co-rotating t...
Design, optimization and testing of micro-evaporator and micro-condenser components used in a miniature vapor compression refrigeration cycle Türkakar, Göker; Okutucu Özyurt, Hanife Tuba; Department of Mechanical Engineering (2016) This study aims to optimize the dimensions and operating conditions of two main components of a miniature vapor compression refrigeration cycle (MVCRC), evaporator and condenser by using entropy generation minimization (EGM). In addition, some performance tests are conducted on a MVCRC which is constructed based on the EGM analysis as long as the manufacturing constraints permit. R134a is used as the coolant. Entropy generation rate in the evaporator of the MVCRC is investigated under the effects of exit va...
Broadband THz Modulators Based on Multilayer Graphene on PVC KAYA, Emine; Kakenov, Nurbek; Kocabas, Coskun; Altan, Hakan; Esentürk, Okan (2016-09-30) In this study we present the direct terahertz timedomain spectroscopic measurement of CVD-grown multilayer graphene (MLG) on PVC substrate with an electrically tunable Fermi level. In a configuration consisting MLG and injected organic dopant, the transmitted intensity loss of terahertz radiation was observed with an applied voltage between 0 and 3.5 V.We showed that MLG on PVC devices provided approximately 100 % modulation between 0.2 and 1.5 THz at preferentially low operation voltage of ca. 3V. The obse...
