  • Chaotic structures in conductivity mechanisms 
    Yıldırım, H. Ahmet. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    Chaotic behavior in the transient current through thin Aluminum-PMMA-Alu-minum films has been analyzed for times ranging up to 30000s, in the temperaturerange 293-363 K for applied voltages in the range 10-80V. The general ...
  • Chaoticity analysis of the current through pure, hydrogenated and hydrophobically modified PEG-SI thin films under varying relative humidity 
    Atak, Kaan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2009., 2009.)
    Polyethylene Glycol is known to have an irregular current characteristic under constant voltage and slowly varying relative humidity. In this study the current through a thin film of Gamma-isocyanatopropyltriethoxysilane ...
  • Detection of optical frequencies of metal-oxide-metal junctions 
    Yanardağ, Sırma Başak. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this thesis, optoelectronic characteristics of metal-oxide-metal junctions are investigated. The junctions are made of aluminum. The detected current in the Al ¡ Al2O3¡Al films is due to a quantum mechanical phenomena; ...
  • Dynamic properties of soft magnetic materials in the shape of thin films and ribbons 
    Kılınç, Muhammed Hasan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    For the last two decades, the giant magneto impedance (GMI) effect has been studied mainly because of its potential use in high sensitivity magnetic field sensors. Nonetheless, magneto impedance response is not only important ...
  • Effects of gases on optical properties of polyethylene glycol 
    Bilen, Bükem. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Humidity induced changes in the refractive index and thickness of polyethylene glycol (PEG) thin films are in situ determined by optical waveguide spectroscopy. PEG brushes are covalently attached to the surface of a thin ...
  • Effects of humidity and various gases on the electrical conductivity of polyethylene glycol 
    Erdamar, Özgül. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Characterization of the electrical properties of covalently linked pure, hydrogenated and hydrophobically modified poly{ethylene glycol} (PEG) thin films under a changing relative humidity is examined by dc measurements. ...
  • Photoacoustic spectroscopy 
    Çolak, Arzu. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In its broadest sense, optical spectroscopy can be defined as the study of the interaction of light with matter. Optical spectroscopy is invaluable in studies on clean media but there are several instances where it is ...
  • Possible chaoticity in condensed matter system 
    Aybar, Orhan Özgür. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    Thin films of polymers are expected to have irregular transient current characteristics under constant voltage. In polymers with water absorbing property such as Polyethylene Glycol, the irregularity also depends on the ...
  • Simulation of transient curret through polymethylmathacrylate thin films based on a charge density wave model 
    Şahin, Gökhan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    A piecewise continuous, time dependent di®usive coupling in a classical onedimensional randomly pinned charge density wave model has been used for the analysisof experimentally observed transient current data for ...
  • Structural characterization of NiMnX (Sn, In) thin film alloys 
    Güvenç, Sema. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Ferromagnetic Ni-Mn-X (Sn, In) alloys are predicted as potential candidates for energy e cient Magnetocaloric E ect (MCE) technologies. The MCE is the basis of magnetic refrigeration and it is expected to leads to a ...
