  • D.C. photoconductivity in As2Se3 thin films 
    Atak, Kaan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2003., 2003.)
    In this thesis, the D.C. photoconductivity in amorphous thin films of As2Se3 is investigated. The temperature dependence of dark, and photo currents are explored at the interval 240 - 360 K. Three regimes are observed in ...
  • Determination of optical constants of thin films 
    Yıldız, Ali. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1998., 1998.)
    In this thesis, a new approach is explored to determine the optical constants of thin dielectric layers. This study is based on the measurement of the reflection at various angles to determine the optical constants of a ...
  • Görülen ışığa duyarlı, ince filmle yapılmış bir optoelektronik aygıt 
    Iskarlatos, Yani. (Thesis (Assoc. Prof.) - Bogazici University. Institute of Sciences and Engineering, 1978., 1978.)
  • Measurement of physical and optical properties of thin films with an ellipsometric technique 
    Ertuğrul, Emine. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    In this thesis, working mechanism of ellipsometer is studied in details. Thickness and refractive index of polyethyleneglycol(PEG), gold and silicon dioxide lms are measured using an elipsometer. PEG is attached to a gold ...
  • 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 ...
  • Purcell effect in polymer films 
    Sarpkaya, İbrahim. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this thesis, the Purcell effect in polymer thin films is studied. According to the Purcell effect, fluorescence of an atom or molecule can be enhanced or inhibited when it is confined to microcavity. As an application ...
  • 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 ...
