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...
Electro-chemo-mechanical induced fracture modeling in proton exchange membrane water electrolysis for sustainable hydrogen production
Aldakheel, Fadi; Kandekar, Chaitanya; Bensmann, Boris; Dal, Hüsnü; Hanke-Rauschenbach, Richard (2022-10-01)
This work provides a framework for predicting fracture of catalyst coated membrane (CCM) due to coupled electro-chemo-mechanical degradation processes in proton exchange membrane water electrolysis (PEMWE) cells. Electrolysis in the catalyst layer (CL) bulk, diffusion of Hydrogen proton through the membrane (MEM), and mechanical compression at the interface with the porous transport layer (PTL) generate micro-cracks that influence the catalyst degradation. Based on our experimental observations, we propose ...
Terahertz mobility measurements on poly-3-hexylthiophene films: Device comparison, molecular weight, and film processing effects
Esentürk, Okan; Heilweil, Edwin J. (2008-01-15)
We directly compare relative carrier mobilities in semiconducting organic polymer films measured using noncontact optical pump terahertz (THz) probe spectroscopy to those reported in electrical device studies. Relative transient signal amplitude measurements of photoinjected carrier mobility as a function of poly-3-hexylthiophene (P3HT) molecular weight correlate directly with electrical device test values, indicating that the THz method shows promise as a rapid material screening approach. We also present ...
