  • Archaelogical provenancing of marble by pore size analysis, using phase transition porosimetry 
    Öztürk, M. Kaan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1999., 1999.)
    Determination of the source of a particular marble sample is an ongoing subject of study among archaeometrists. In this study, categorization according to pore size distribution is suggested. The employed method for pore ...
  • 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 density of states of n-type hydrogenated amorphous silicon by phase shift analysis of modulated photocurrent method 
    Kocabıyık, Ferhat. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1995., 1995.)
    Determination of density of states of hydrogenated amorphous siliconby phase shift analysis of modulated photocurrent.Determination of the energetic distribution of localized statesdue to random network and structural ...
  • Electro optical characterization of a silicon microsphere 
    Ayaz, Ulaş Kemal. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In today’s world, with the development of optoelectronics, metal interconnections are no longer limiting factor for the performance of electronic systems. Replacing the metal interconnections by optical interconnections ...
  • Frequency-resolved photoconductivity studies in amorphous chalcogenide films 
    Akat, Ercüment. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2000., 2000.)
    Frequency-resolved photocurrent measurements (FRPC) were carried out on amorphous chalcogenide films such as AsSeSb AsSe and AsSeTe, by a method called frequency-resolved spectroscopy (FRS) as a function of temperature ...
  • Study of teh D.C conductance mechanism of evaporated amorphous silicon films 
    Atağ, Yılmaz. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1984., 1984.)
    In this thesis the d.c bulk characteristis of amorphous silicon films are investigated. The films are prepared by electron gun evaporation in a conventional vacuum system. Ohmic contacts are established between the silicon ...
  • Study of the AC conductance mechanism of evaporated amorphous silicon films 
    Gülsoy, Ayhan O. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1986., 1986.)
