Preparation of BTS-BCT thin films by chemical solution deposition and their characterization /
Akbay, Berk; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2015)
In the presented thesis, lead-free Ba(Ti0.88Sn0.12)O3-0.3(Ba0.7Ca0.3)TiO3 (BTS-BCT) thin films were deposited on (111)-Pt/TiO2/SiO2/(100)-Si substrates using chemical solution deposition method and then the effect of process parameters were investigated to obtain optimum parameters of these lead-free thin films. The phase was selected near to the morphotropic phase boundary (MPB) to increase the number of polarization directions where rhombohedral and tetragonal phases exist together. In this study, the eff...
Measurement of the cross section ratio σ(χc₂)/σ(χc₁) for prompt χc production with CMS experiment
Akin, Ilina Vasileva; Zeyrek, Mehmet Tevfik; Department of Physics (2012)
The prompt production of χc quarkonia is studied in proton-proton collisions at 7 TeV, using data collected by CMS in 2011 corresponding to an integrated luminosity of 4.6 fb −1. The χc mesons are reconstructed through their radiative decays to J/ψ and photon with J/ψ → μ+μ− . The photons are reconstructed through their conversion in electron-positron pairs in the tracking detector which gives a mass resolution sufficient for resolving these states. The ratio of the prompt production ₁cross sections for the...
Preparation of BaxSr1-xTiO3 thin films by chemical solution deposition and their electrical characterization
Adem, Umut; Özenbaş, Ahmet Macit; Department of Metallurgical and Materials Engineering (2003)
In this study, barium strontium titanate (BST) thin films with different compositions (Ba0.9Sr0.1TiO3, Ba0.8Sr0.2TiO3, Ba0.7Sr0.3TiO3, Ba0.5Sr0.5TiO3) were produced by chemical solution deposition technique. BST solutions were prepared by dissolving barium acetate, strontium acetate and titanium isopropoxide in acetic acid and adding ethylene glycol as a chelating agent and stabilizer to this solution, at molar ratio of acetic acid/ethylene glycol, 3:1. The solution was then coated on Si and Pt//Ti/SiO2/Si ...
Structural, optical and electrical characterization of CDSEXTE1-X thin films
Demir, Merve; Parlak, Mehmet; Department of Physics (2020)
The aim of this study is to investigate the structural, optical and electrical properties of ternary CdSexTe1-x thin films. CdTe and CdSe thin films are being used in solar cells due to their favorable direct band gaps of 1.5eV and 1.7eV, respectively. Moreover, having high absorption coefficients provide an important role to CdTe and CdSe films as an absorber layer. Therefore, by mixing these two films, properties of resultant ternary CdSexTe1-x alloy can be optimized for solar cell applications. Chemical ...
DDS based MIL-STD-1553B data bus interface simulation
Deniz, Ertan; Oğuztüzün, Mehmet Halit S.; Durak, Umut; Department of Computer Engineering (2012)
This thesis describes distributed simulation of MIL-STD-1553B Serial Data Bus interface and protocol based on the Data Distribution Service (DDS) middleware standard. The data bus connects avionics system components and transports information among them in an aircraft. It is important for system designers to be able to evaluate and verify their component interfaces at the design phase. The 1553 serial data bus requires specialized hardware and wiring to operate, thus it is expensive and complex to verify co...
