Implications of tunneling studies on high-Tc cuprates: Superconducting gap and pseudogap
(Elsevier, 2001-11)
Tunneling spectra have been measured on high-Tc cuprates including single crystals Bi2Sr2-xLaxCuO6+δ (Bi2201) and Bi2Sr2CaCu2O8+δ (Bi2212) using superconductor-insulator-normal metal point contact or superconductor-insul ...
Persistence of strong electron coupling to a narrow boson spectrum in overdoped Bi2Sr2CaCu2O8+Î tunneling data
(American Physical Society, 2006-01)
A d-wave, Eliashberg analysis of break-junction and STM tunneling spectra on Bi2Sr2CaCu2O8+Î (Bi2212) reveals that the spectral dip feature is directly linked to strong electronic coupling to a narrow boson spectrum, ...
Cu2ZnSnS4-based thin films and solar cells by rapid thermal annealing processing
(Elsevier, 2017-04)
In this study, kesterite Cu2ZnSnS4 (CZTS) absorber layers were fabricated by DC magnetron sputtering deposition of metallic Cu-Zn-Sn precursors, followed by an annealing treatment in sulfur vapor atmosphere at 600 °C for ...
Effect of Al substitution on structural and electrical properties of Bi1.6Pb0.4Sr2CaCu2-x Mx O8+δ superconducting ceramics
(Springer, 2013-04)
In this work we study the effect on structural and electrical properties of superconducting compound Bi1.6Pb0.4Sr 2CaCu2-y My O8+δ were M=Al (with y=0-0.6). The samples were prepared by the solid-state reaction method. The ...
Metal mesh filters based on Ti, ITO and Cu thin films for terahertz waves
(Springer, 2016-02-01)
In this study, we have investigated the spectral performance of resonant terahertz (THz) bandpass filters which were produced from thin films with a metal-mesh shape. The aforementioned filters were fabricated from titanium, ...
The effects of Sb substitution on structural properties in YBa 2Cu 3O 7 superconductors
(Springer, 2011-11)
In this study, the effects of partial Sb 3+ ion substitutions for the Y sites and the Cu sites on the superconducting properties of YBa 2Cu 3O y (Y123) ceramic superconductors were investigated. The samples were prepared ...
Comparision of in situ spectroscopic ellipsometer and ex situ x-ray photoelectron spectroscopy depth profiling analysis of HfO2/Hf/Si multilayer structure
(Institute of Physics Publishing, 2018-09)
A HfO2 film was grown by RF magnetron sputtering technique on a Si substrate Using in situ Spectroscopic Ellipsometry (SE), the film thickness and refractive index were examined as a function of deposition time. Ex situ ...
Improvement of optical and electrical properties of ITO thin films by electro-annealing
(Elsevier, 2015-10)
The effect of electro-annealing in vacuum and air on the optical and electrical properties of ITO thin films grown by large area DC magnetron sputtering was investigated. Moreover, the performances of the electro-annealed ...
Investigation of electron beam lithography effects on metal-insulator transition behavior of vanadium dioxide
(IOP Publishing, 2017-10)
Vanadium dioxide (VO2) shows metal-insulator phase transition at nearly 68 °C. This metal-insulator transition (MIT) in VO2 leads to a significant change in near-infrared transmittance and an abrupt change in the resistivity ...
An indium tin oxide metasurface filter for terahertz applications: Design, fabrication, and characterization
(World Scientific Publishing, 2017-03)
In this paper, using a cross-shaped complementary Indium Tin Oxide (ITO)-based metasurface design, the transmission of THz radiation is shown to be filtered within the 3 dB level from maximum in the frequency range of ...
