    • LSPR enhanced MSM UV photodetectors 

      Butun, S.; Cinel, N. A.; Ozbay, E. (IOP Publishing, 2012-10-18)
      We fabricated localized surface plasmon resonance enhanced UV photodetectors on MOCVD grown semi-insulating GaN. Plasmonic resonance in the UV region was attained using 36nm diameter Al nanoparticles. Extinction spectra ...
    • Nanoplasmonic three-dimensional surfaces with strong surface-normal electric field enhancement 

      Gungor, K.; Unal, E.; Demir, H. V. (2013)
      Conventional plasmonic structures provide field enhancement in the plane. The proposed nanoplasmonic three-dimensional surfaces, with unity coverage in the plan-view, enable surface-normal enhancement and achieve 7.2-fold ...
    • Raman enhancement on a broadband meta-surface 

      Ayas S.; Güner, H.; Türker, B.; Ekiz, O. O.; Dirisaglik, F.; Okyay, A., K.; Dâna, A. (American Chemical Society, 2012-07-30)
      Plasmonic metamaterials allow confinement of light to deep subwavelength dimensions, while allowing for the tailoring of dispersion and electromagnetic mode density to enhance specific photonic properties. Optical resonances ...
    • SILVER nano-cylinders designed by EBL used as label free LSPR nano-biosensors 

      Cinel, N.A.; Bütün, S.; Özbay, E. (2011)
      Localized Surface Plasmon Resonance (LSPR) is based on the electromagnetic-field enhancement of metallic nano-particles. It is observed at the metal-dielectric interface and the resonance wavelength can be tuned by the ...
    • Three-dimensional nanoplasmonic surfaces with strong out-of-plane electric field enhancement 

      Demir, H. V.; Güngör, K.; Ünal, E. (2013)
      Conventional 2D plasmonic structures, with surface coverage ~50%, provide field enhancement in the plane. The proposed 3D nanoplasmonic surfaces, with unity coverage, achieve 7.2-fold stronger out-of-plane enhancement ...
    • Universal infrared absorption spectroscopy using uniform electromagnetic enhancement 

      Ayas S.; Bakan, G.; Ozgur E.; Celebi, K.; Dana, A. (American Chemical Society, 2016)
      Infrared absorption spectroscopy has greatly benefited from the electromagnetic field enhancement offered by plasmonic surfaces. However, because of the localized nature of plasmonic fields, such field enhancements are ...
