    • Arrays of suspended plasmonic nanodiscs 

      Uran, Can; Demir, Hilmi Volkan (IEEE, 2013)
      We demonstrate lateral arrays of suspended metal nanodiscs, erected in parallel, partially encased in a dielectric-wrap using in-template synthesis with their polarization-dependent properties controlled as a function of ...
    • Heterodoped manoparticles as dual-mode contrast agent for MRI 

      Alipour, Akbar; Sharma, Vijay Kumar; Soran-Erdem, Zeliha; Kelestemur, Yusuf; Aykut, Zaliha Gamze; Demir, Hilmi Volkan (IEEE, 2018)
      The purpose of this work is to synthesize Mn-Fe heterodoped ZnSe tetrapod nanocrystals (NCs) as dualmode MRI contrast agent to offer synergetic beneficial over the single contrast tracer. Also, in vivo feasibility of the ...
    • Nanocrystal optoelectronics for quality lighting and displays 

      Tan, S. T.; Demir, Hilmi Volkan (Optical Society of America, 2013)
      We review the recent advances in color-conversion LEDs integrating nanophosphors of semiconductor quantum dots for quality lighting and displays in our group. © OSA 2013.
    • Single ultrafast diffusive conduction based optoelectronic switch for multi-channel operation 

      Köklü, Fatih Hakan; Demir, Hilmi Volkan; Yairi, M.; Harris Jr. J.S.; Miller, D.A.B. (IEEE, 2005)
      For multi-channel optical switching, we report single ultrafast diffusive conduction based optoelectronic switches that accommodate >100 optical channels (with 2,000mm-2 channel density and <10% crosstalk), on ...
