Electrochromic switching of WO3 nanostructures and thin films
Karakurt, İsmail; Boneberg, Johannes; Leiderer, Paul (Springer-Verlag, 2006-04)We present transmission measurements through tungsten tri-oxide nanostructures and thin films prepared by sol-gel process on micro-contact printed substrates. Identical electrochromic switching times are found for both the ... -
Nonreciprocal switching of VO2 thin films on microstructured surfaces
Karakurt, İsmail; Adams, Charles H; Leiderer, Paul; Boneberg, Johannes; Haglund, Richard F. (Optical Soc Amer, 2010-05-15)We demonstrate that the combination of near-field focusing and a switchable oxide layer permits construction of a modulator with different optical switching thresholds in two opposing directions. For that purpose VO2 layers ... -
Size-dependent self-organization of colloidal particles on chemically patterned surfaces
Karakurt, İsmail; Leiderer, Paul; Boneberg, Johannes (SP Zhejiang University Press, 2006-04-14)A study of the self-organization of colloidal particles during the evaporation of particle solutions on chemically patterned surfaces is presented. On a surface with hydrophilic and hydrophobic regions, colloidal particles ... -
Time-dependent lateral diffusion in WO₃ thin films
Karakurt, İsmail; Başar, Günay; Leiderer, Paul; Parlatan, Şeyma; Arapoğlu, Nihan (Elsevier B.V., 2023-10)We have studied the anomalous lateral diffusion process in thin tungsten trioxide films by optical means. The diffusion process seems to start at imperfections within the film a few seconds after the H+ ion intercalation ... -
Transmission increase upon switching of VO2 thin films on microstructured surfaces
Karakurt, İsmail; Boneberg, Johannes; Leiderer, Paul; Lopez, Rene; Halabica, A.; Haglund, Richard F. (American Institute of Physics, 2007-08-27)The authors compare transmission measurements of near-infrared light through VO2 thin films on smooth substrates and on ordered arrays of silica microspheres. When the samples are heated above the critical temperature for ...
