Publication Macroscopic Assembly of Indefinitely Long and Parallel Nanowires into Large Area Photodetection Circuitry(AMER CHEMICAL SOC, 2012) Ozgur, Erol; Aktas, Ozan; Kanik, Mehmet; Yaman, Mecit; Bayindir, Mehmet; Yaman, Mecit; Ihsan Dogramaci Bilkent University; Ihsan Dogramaci Bilkent University; Ihsan Dogramaci Bilkent University; Ministry of Science, Industry & Technology - Turkey; Turk Hava Kurumu University; Turkish Aeronautical AssociationIntegration of nanowires into functional devices with high yields and good reliability turned out to be a lot more challenging and proved to be a critical issue obstructing the wide application of nanowire-based devices and exploitation of their technical promises. Here we demonstrate a relatively easy macrofabrication of a nanowire-based imaging circuitry using a recently developed nanofabrication technique. Extremely long and polymer encapsulated semiconducting nanowire arrays, mass-produced using the iterative thermal drawing, facilitate the integration process; we manually aligned the fibers containing selenium nanowires over a lithographically defined circuitry. Controlled etching of the encapsulating polymer revealed a monolayer of nanowires aligned over an area of 1 cm(2) containing a 10 x 10 pixel array. Each light-sensitive pixel is formed by the contacting hundreds of parallel photoconductive nanowires between two electrodes. Using the pixel array, alphabetic characters were identified by the circuitry to demonstrate its imaging capacity. This new approach makes it possible to devise extremely large nanowire devices on planar, flexible, or curved substrates with diverse functionalities such as thermal sensors, phase change memory, and artificial skin.Publication Macroscopic Assembly of Indefinitely Long and Parallel Nanowires into Large Area Photodetection Circuitry(American Chemical Society (ACS), 2012-04-13) Erol Ozgur; Ozan Aktas; Mehmet Kanik; Mecit Yaman; Mehmet Bayindir; Yaman, MecitPublication Structural Coloring in Large Scale Core–Shell Nanowires(American Chemical Society (ACS), 2011-10-21) Tural Khudiyev; Erol Ozgur; Mecit Yaman; Mehmet Bayindir; Yaman, MecitPublication Bioinspired Optoelectronic Nose with Nanostructured Wavelength‐Scalable Hollow‐Core Infrared Fibers(Wiley, 2010-12-20) Adem Yildirim; Mert Vural; Mecit Yaman; Mehmet Bayindir; Yaman, MecitPublication High Selectivity Boolean Olfaction Using Hollow-Core Wavelength-Scalable Bragg Fibers(American Chemical Society (ACS), 2011-12-14) Mecit Yaman; Adem Yildirim; Mehmet Kanik; Tugrul C. Cinkara; Mehmet Bayindir; Yaman, MecitPublication All-chalcogenide glass omnidirectional photonic band gap variable infrared filters(AIP Publishing, 2009-03-16) H. Esat Kondakci; Mecit Yaman; Ozlem Koylu; Aykutlu Dana; Mehmet Bayindir; Yaman, MecitWe report on the design, fabrication, and characterization of spatially variable infrared photonic band gap filter that consists of thermally evaporated, high refractive index contrast, amorphous chalcogenide glass multilayers. Due to graded thickness structure, the filter exhibits a position dependent stop band and a cavity mode ranging from 1.8 to 3.4 μm wavelengths. Reflection measurements on the variable filter agree well with theoretical calculations. These results pave the way to low-loss infrared mirrors, filters, spectral imaging, and miniaturized spectrometers at infrared region.Publication Template free preparation of nanoporous organically modified silica thin films on flexible substrates(Royal Society of Chemistry (RSC), 2011) Adem Yildirim; Hulya Budunoglu; Mecit Yaman; Mustafa O.
