Controlling the photoconductivity: graphene oxide and polyaniline self assembled intercalation
Vempati S.; Ozcan, S.; Uyar, Tamer (American Institute of Physics Inc., 2015)We report on controlling the optoelectronic properties of self-assembled intercalating compound of graphene oxide (GO) and HCl doped polyaniline (PANI). Optical emission and X-ray diffraction studies revealed a secondary ... -
Effects of rapid thermal annealing on the structural and local atomic properties of ZnO: Ge nanocomposite thin films
Ceylan, A.; Rumaiz, A. K.; Caliskan, D.; Ozcan, S.; Özbay, Ekmel; Woicik, J. C. (A I P Publishing LLC, 2015)We have investigated the structural and local atomic properties of Ge nanocrystals (Ge-ncs) embedded ZnO (ZnO: Ge) thin films. The films were deposited by sequential sputtering of ZnO and Ge thin film layers on z-cut quartz ... -
Magnetotransport study on AlInN/(GaN)/AlN/GaN heterostructures
Bayrakli, A.; Arslan, E.; Firat, T.; Ozcan, S.; Kazar, O.; Cakmak, H.; Özbay, Ekmel (Wiley, 2012-02-27)We report the effect of a thin GaN (2?nm) interlayer on the magnetotransport properties of AlInN/AlN/GaN-based heterostructures. Two samples were prepared (Sample A: AlInN/AlN/GaN and sample B: AlInN/GaN/AlN/GaN). Van der ... -
Metal-semiconductor-metal photodetector on as-deposited TiO2 thin films on sapphire substrate
Caliskan, D.; Butun, B.; Ozcan, S.; Özbay, Ekmel (AIP Publishing LLC, 2013-03-06)TiO2 thin films are prepared on c-plane sapphire substrates by the RF magnetron sputtering method. The performance of the Pt contact metal–semiconductor–metal (MSM) photodetector fabricated on as-deposited films is studied. ... -
Spectral response modification of TiO2 MSM photodetector with an LSPR filter
Caliskan, D.; Butun, B.; Ozcan, S.; Özbay, Ekmel (Optical Society of America, 2014)We fabricated UVB filtered TiO2 MSM photodetectors by the localized surface plasmon resonance effect. A plasmonic filter structure was designed using FDTD simulations. Final filter structure was fabricated with Al ...
