The ambient stability of thin-film transistors (TFTs) based on zinc oxide (ZnO) nanowires embedded in poly (3,3'''-dialkyl-quarterthiophene) was monitored through time dependence of electrical characteristics over a period of 16 months. The hybrid-based TFT showed an initial hole mobility in the linear regime of 4.2 x 10(-4) cm(2)/V s. After 16 months storage in ambient conditions (exposed to air, moisture, and light) the mobility decreased to 2.3 x 10(-5) cm(2)/V s. Comparatively the organic-based TFT lost total carrier mobility after one month storage making the hybrid-based TFTs more suitable for transistor applications when improved stability combined with structural flexibility are required.

Zinc oxide nanowire networks for macroelectronic devices Ünalan, Hüsnü Emrah; Hiralal, Pritesh; Dalal, Sharvari; Chu, Daping; Eda, Goki; Teo, K. B. K.; Chhowalla, Manish; Milne, William I.; Amaratunga, Gehan A. J. (AIP Publishing, 2009-04-20) Highly transparent zinc oxide (ZnO) nanowire networks have been used as the active material in thin film transistors (TFTs) and complementary inverter devices. A systematic study on a range of networks of variable density and TFT channel length was performed. ZnO nanowire networks provide a less lithographically intense alternative to individual nanowire devices, are always semiconducting, and yield significantly higher mobilites than those achieved from currently used amorphous Si and organic TFTs. These r...
Electric dipole moments of charged leptons and lepton flavor violating interactions in the general two Higgs doublet model Iltan, EO (American Physical Society (APS), 2001-07-01) We calculate the electric dipole moment of the electron using the experimental result of the muon electric dipole moment and upper limit of the BR(mu-->e gamma) in the framework of the general two Higgs doubler model. Our prediction is 10(-32) e cm, which lies in the experimental current limits. Further, we obtain constraints for the Yukawa couplings )over bar>(D)(N,taue) and )over bar>(D)(N,tau mu). Finally, we present an expression which connects the BR(tau-->mu gamma) and the electric dipole moment of th...
Stable, self-ballasting field emission from zinc oxide nanowires grown on an array of vertically aligned carbon nanofibers Li, C.; Zhang, Y.; Mann, M.; Hiralal, P.; Ünalan, Hüsnü Emrah; Lei, W.; Wang, B. P.; Chu, D. P.; Pribat, D.; Amaratunga, G. A. J.; Milne, W. I. (AIP Publishing, 2010-04-05) A structure composed of zinc oxide nanowires (ZNWs) grown hydrothermally on an array of vertically aligned carbon nanofibers (CNFs) was fabricated and its field emission properties determined and compared with bare CNF arrays. The combination produced a macroscopic turn-on field of 1.2 V/mu m which was found to be the lowest reported from ZNWs deposited on a two-dimensional substrate and much less than the equivalent CNFs array (5.2 V/mu m). Crucially, field emission was found to be much more stable at high...
Novel RDX-Based Cage and Cage-Like Nitramines Türker, Burhan Lemi; Bayar, Caglar Celik; Turhan, Hamza (Informa UK Limited, 2013-10-01) 1,3,5-Trinitroperhydro-1,3,5-triazine (RDX)-based cage and cage-like nitramines in which two RDX molecules are linked to each other via three and two carbon atoms, respectively, have been investigated computationally using density functional theory (DFT) at a B3LYP/6-31G(d,p) theoretical level. The study focused on finding out how the quantum chemical and detonation properties of RDX change if two RDX molecules come together and form these structures. Both considered nitramines exhibited higher heats of for...
Nanoscale charging hysteresis measurement by multifrequency electrostatic force spectroscopy Bostanci, Umut; Abak, M. Kurtulus; AKTAŞ, Özgür; DANA, Aykutlu (AIP Publishing, 2008-03-03) We report a scanning probe technique that can be used to measure charging of localized states on conducting or partially insulating substrates at room temperature under ambient conditions. Electrostatic interactions in the presence of a charged particle between the tip and the sample is monitored by the second order flexural mode, while the fundamental mode is used for stabilizing the tip-sample separation. Cycling the bias voltage between two limits, it is possible to observe hysteresis of the second order...
