Atomic Layer Deposition for Vertically Integrated ZnO Thin Film Transistors: Toward 3D High Packing Density Thin Film Electronics
(Wiley-VCH Verlag, 2017)We report on the first demonstration of the atomic layer deposition (ALD) based three dimensional (3D) integrated ZnO thin film transistors (TFTs) on rigid substrates. Devices exhibit high on-off ratio (∼106) and high ... -
Atomic-layer-deposited zinc oxide as tunable uncooled infrared microbolometer material
(Wiley-VCH Verlag, 2014)ZnO is an attractive material for both electrical and optical applications due to its wide bandgap of 3.37 eV and tunable electrical properties. Here, we investigate the application potential of atomic-layer-deposited ZnO ... -
Co doping induced structural and optical properties of sol-gel prepared ZnO thin films
(Elsevier BV, 2014-11)The preparation conditions for Co doping process into the ZnO structure were studied by the ultrasonic spray pyrolysis technique. Structural and optical properties of the Co:ZnO thin films as a function of Co concentrations ... -
Concentric ring structures as efficient SERS substrates
(Institute of Electrical and Electronics Engineers, 2013)Plasmonic nanopatterned structures that can work as highly efficient surface-enhanced Raman scattering (SERS) substrates are presented in this study. A 'coupled' concentric ring structure has been designed, fabricated, ... -
Low temperature atomic layer deposited ZnO photo thin film transistors
(AVS Science and Technology Society, 2014)ZnO thin film transistors (TFTs) are fabricated on Si substrates using atomic layer deposition technique. The growth temperature of ZnO channel layers are selected as 80, 100, 120, 130, and 250°C. Material characteristics ... -
Low-temperature grown wurtzite InxGa1−xN thin films via hollow cathode plasma-assisted atomic layer deposition
(Royal Society of Chemistry, 2015-08)Herein, we report on atomic layer deposition of ternary InxGa1−xN alloys with different indium contents using a remotely integrated hollow cathode plasma source. Depositions were carried out at 200 °C using organometallic ... -
Non-linear thermoelectricity and cooling effects in metallic constrictions
(Institute of Physics Publishing Ltd., 1994)Linear as well as non-linear contributions to the Zeebeck and Peltier coefficients of a metallic film in contact with the equilibrium metal are calculated within a simple model. The non-linear part of the thermoelectric ... -
Optical characteristics of nanocrystalline AlxGa1-xN thin films deposited by hollow cathode plasma-assisted atomic layer deposition
(AVS Science and Technology Society, 2014)Gallium nitride (GaN), aluminum nitride (AlN), and AlxGa 1-xN films have been deposited by hollow cathode plasma-assisted atomic layer deposition at 200 °C on c-plane sapphire and Si substrates. The dependence of film ... -
Quantum transport through one-dimensional aluminum wires
(American Vacuum Society, 2002)Quantum conductance in narrow channels has been well understood by using the two-dimensional electron gas, a model system which has been realized in semiconductor heterojunctions. An essential property of this electron ... -
Room-temperature larger-scale highly ordered nanorod imprints of ZnO film
(Optical Society of American (OSA), 2013)Room-temperature large-scale highly ordered nanorod-patterned ZnO films directly integrated on III-nitride light-emitting diodes (LEDs) are proposed and demonstrated via low-cost modified nanoimprinting, avoiding a ... -
Seed layer assisted hydrothermal deposition of low-resistivity ZnO thin films
(Materials Research Society, 2017)In this work, we describe the combination of hydrothermal and atomic layer deposition (ALD) for growing low-resistivity ZnO polycrystalline continuous films. The effect of the thickness of ALD seed layers on the morphology ... -
Strong coupling between localized and propagating plasmon polaritons
(OSA - The Optical Society, 2015)We investigate plasmon-plasmon (PP) coupling in the strongly interacting regimes by using a tunable plasmonic platform consisting of triangular Ag nanoprisms placed nanometers away from Ag thin films. The nanoprisms are ... -
Synthesis and optical properties of Co and Zn-based metal oxide nanoparticle thin films
(Polish Academy of Sciences, 2017)ZnO, Co doped ZnO (ZnO:Co) and CoO thin films were deposited on glass substrates by using the spark discharge technique with Zn-Zn, Zn-Co and Co-Co metal electrodes (tips). The structural and optical properties of the films ... -
