    • 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 ...
    • Skin-like self-assembled monolayers on InAs / GaSb superlattice photodetectors 

      Salihoglu, O.; Muti, A.; Kutluer, K.; Tansel, T.; Turan, R.; Aydınlı, Atilla (IOP Institute of Physics Publishing, 2012)
      We report on the effects of monolayer (ML) thick skin-like octadecanethiol (ODT, CH 3[CH 2] 17SH) on type-II InAs/GaSb MWIR photodetectors. Circumventing the ageing effects of conventional sulfur compounds, we use ODT, a ...
    • Thiol passivation of MWIR Type II superlattice photodetectors 

      Salihoğlu, Ömer; Muti, Abdullah; Aydınlı, Atilla (SPIE, 2013)
      Poor passivation on photodetectors can result in catastrophic failure of the device. Abrupt termination of mesa side walls during pixel definition generates dangling bonds that lead to inversion layers and surface traps ...
