    • Amyloid inspired self-assembled peptide nanofibers 

      Çınar, Göksu; Ceylan, Hakan; Urel, Mustafa; Erkal, Turan S.; Tekin, E. Deniz; Tekinay, Ayse B.; Dâna, Aykutlu; Güler, Mustafa O. (American Chemical Society, 2012)
      Amyloid peptides are important components in many degenerative diseases as well as in maintaining cellular metabolism. Their unique stable structure provides new insights in developing new materials. Designing bioinspired ...
    • Comparison of electron and hole charge-discharge dynamics in germanium nanocrystal flash memories 

      Akça, İmran B.; Dâna, Aykutlu; Aydınlı, Atilla; Turan, R. (AIP Publishing, 2008-02)
      Electron and hole charge and discharge dynamics are studied on plasma enhanced chemical vapor deposition grown metal-oxide-silicon germanium nanocrystal flash memory devices. Electron and hole charge and discharge currents ...
    • Electro-optic modulation of InAs quantum dot waveguides 

      Akça, İmran. B.; Dâna, Aykutlu; Aydınlı, Atilla; Rossetti, M.; Li, L.; Fiore, A.; Dağlı, N. (Technische Universiteit Eindhoven, 2008)
      The linear electro-optic properties in waveguides containing self-organized In As quantum dots were studied experimentally. Fabry-Perot measurements at 1515 nm on InAs/GaAs quantum dot structures yield a significantly ...
    • Grating coupler integrated photodiodes for plasmon resonance based sensing in fluidic systems 

      Türker, Burak; Güner, Hasan; Ayaş, Sencer; Ekiz, Okan O.; Acar, Handan; Güler, Mustafa O.; Dâna, Aykutlu (IEEE, 2011)
      We demonstrate an integrated sensor combining a grating-coupled plasmon resonance surface with a planar photodiode. Plasmon enhanced transmission is employed as a sensitive refractive index (RI) sensing mechanism and ...
    • Nanomechanical characterization by double-pass force-distance mapping 

      Dagdas, Yavuz S.; Aslan, M. N.; Tekinay, Ayse B.; Güler, Mustafa O.; Dâna, Aykutlu (Institute of Physics Publishing, 2011)
      We demonstrate high speed force-distance mapping using a double-pass scheme. The topography is measured in tapping mode in the first pass and this information is used in the second pass to move the tip over the sample. In ...
    • Spectroscopic ellipsometric study of Ge nanocrystals embedded in SiO 2 using parametric models 

      Basa, P.; Petrik, P.; Fried, M.; Dâna, Aykutlu; Aydınlı, Atilla; Foss, S.; Finstad, T. G. (Wiley, 2008-05)
      Ge-rich SiO2 layers on top of Si substrates were deposited using plasma enhanced chemical vapour deposition. Ge nanocrystals embedded in the SiO2 layers were formed by high temperature annealing. The samples were measured ...
