    • Ab-initio study of iridium on silicon (001) surface 

      Oğuz, İsmail Can (Bilkent University, 2013)
      Self-assembled nanowire growth on semiconductor surface is based on deposing sub-monolayer material over the surface. Even though high resolution STM image gives plausible surface analysis, determination of the nanowire ...
    • Beaming and localization of electromagnetic waves in periodic structures 

      Çağlayan, Hümeyra (Bilkent University, 2010)
      We want to manipulate light for several applications: microscopy, data storage, leds, lasers, modulators, sensor and solarcells to make our life healthier, easier or more comfortable. However, especially in small scales ...
    • Computation of surface fields excited on arbitrary smooth convex surfaces with an impedance boundary condition 

      Alişan, Burak (Bilkent University, 2012)
      Due to an increase in the use of conformal antennas in military and commercial applications, the study of surface fields excited by a current distribution on material coated perfect electric conductor (PEC) surfaces is ...
    • Coupled surface plasmon structures and applications 

      Gürel, Kemal (Bilkent University, 2009)
      Surface plasmons have attracted great interest during past decades due to their unique physical properties. In this thesis, we study grating-coupled surface plasmons for sensing and filtering applications. We first present ...
    • Fabrication, characterization and simulation of plasmonic cavities 

      Karabıyık, Mustafa (Bilkent University, 2010)
      Surface plasmon polaritons (SPPs) originate from the collective oscillations of conduction electrons coupled with photons propagating at metal-dielectric interfaces. A uniform metallic gratings change the dispersion ...
    • Grating based plasmonic cavities 

      Şenlik, Servet Seçkin (Bilkent University, 2009)
      Surface plasmon polaritons are dipole carrying electromagnetic excitations occur- ing at metal-dielectric interfaces. Metallic periodic structures exhibit modi¯ed transmission and re°ection spectra owing to the interaction ...
    • Investigation of Si1-xGex alloy formation by using STM 

      Oral, Ahmet (Bilkent University, 1994)
    • Novel techniques in multi-frequency atomic force microscopy and spectroscopy 

      Abak, Musa Kurtuluş (Bilkent University, 2009)
      The capability of measuring material properties of nanostructures simultaneously with their size and shape is very desirable for characterization of novel materials and devices at the nanoscale Here we present two novel ...
    • Plasmonic band gap cavities 

      Kocabaş, Aşkın (Bilkent University, 2008)
      Surface plasmon polaritons (SPP’s) are trapped electromagnetic waves coupled to free electrons in metals that propagate at the metal-dielectric interfaces. Due to their surface confinement and potential in sub-wavelength ...
    • Probing interfacial processes on carbon nanotubes and graphene surfaces 

      Kakenov, Nurbek (Bilkent University, 2012)
      The surface of low-dimensional carbon (carbon nanotubes and graphene) has unique electronic properties due to the delocalized p-orbitals. Very high carrier mobility with nanoscale dimension make carbon nanotubes and ...
    • Subwavelength surface plasmon interferometer for high-throughput sensing 

      Yavaş, Özlem (Bilkent University, 2012)
      Small detection volume, increased analysis speed and reduced cost are the main driving forces for miniaturized lab-on-a-chip systems. Subwavelength holes on opaque metal films provide a unique configuration for miniaturized ...
