    • An array of surface-enhanced Raman scattering substrates based on plasmonic lenses 

      Kahraman, M.; Cakmakyapan, S.; Özbay, Ekmel; Culha, M. (Wiley, 2012-10-01)
      An array of ring-shaped holes is prepared from silver thin films using electron beam lithography. The optimal conditions for high performance as a surface-enhanced Raman scattering (SERS) substrate are investigated. Either ...
    • Cyclodextrin functionalized nanofibers via electrospinning 

      Çelebioğlu, Aslı (Bilkent University, 2014)
      Electrospinning is a commonly studied and widely applied technique for generating nanofibers, with a diameter ranging from several tens of nanometers to a few micrometers. The low-cost, simple set-up, relatively high ...
    • Novel materials and techniques for energy conversion and sensing 

      Ekiz, Okan Öner (Bilkent University, 2015-12)
      In the recent years, characterization of nanomaterials and using them in sensing applications gain considerable attention. Increased research on nanotechnology brings new materials and techniques that come with many ...
    • Plasmonic absorbers for multispectral and broadband absorption 

      Ayaş, Sencer; Güner, Hasan; Türker, Burak; Ekiz, Öner; Dana, Aykutlu (SPIE, 2012)
      We present polarization dependent multispectral and broadband plasmonic absorbers in the visible spectrum. The spectral characteristics of these structures are tunable over a broad spectrum. Experimental results are verified ...
    • 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 ...
    • Tunable plasmonic silver nanodomes for surface-enhanced raman scattering 

      Kahraman, M.; Ozbay, A.; Yuksel, H.; Solmaz, R.; Demir, B.; Caglayan, H. (Springer, 2018)
      Surface-enhanced Raman scattering (SERS) is an emerging analytical method used in biological and non-biological structure characterization. Since the nanostructure plasmonic properties is a significant factor for SERS ...
