    • Demonstration of flexible thin film transistors with GaN channels 

      Bolat, S.; Sisman, Z.; Okyay, A., K. (American Institute of Physics Inc., 2016)
      We report on the thin film transistors (TFTs) with Gallium Nitride (GaN) channels directly fabricated on flexible substrates. GaN thin films are grown by hollow cathode plasma assisted atomic layer deposition (HCPA-ALD) ...
    • Electrically controlled terahertz spatial light modulators with graphene arrays 

      Kakenov, N.; Takan, T.; Ozkan, V. A.; Balci, O.; Polat, E. O.; Altan, H.; Kocabas, C. (Institute of Electrical and Electronics Engineers Inc., 2016)
      Gate-tunable high-mobility electrons on atomically thin graphene layers provide a unique opportunity to control electromagnetic waves in a very broad spectrum. In this paper, we describe an electrically-controlled multipixel ...
    • Flexible and fragmentable tandem photosensitive nanocrystal skins 

      Akhavan S.; Uran, C.; Bozok, B.; Gungor K.; Kelestemur Y.; Lesnyak, V.; Gaponik N.; Eychmüller A.; Demir, H. V. (Royal Society of Chemistry, 2016)
      We proposed and demonstrated the first account of large-area, semi-transparent, tandem photosensitive nanocrystal skins (PNSs) constructed on flexible substrates operating on the principle of photogenerated potential ...
    • Flexible metamaterials for wireless strain sensing 

      Melik, R.; Unal, E.; Perkgoz, N. K.; Puttlitz, C.; Demir, H. V. (American Institute of Physics, 2009-11-04)
      We proposed and demonstrated flexible metamaterial-based wireless strain sensors that include arrays of split ring resonators (SRRs) to telemetrically measure strain. For these metamaterial sensors, we showed that a flexible ...
    • Highly flexible, electrically driven, top-emitting, quantum dot light-emitting stickers 

      Yang X.; Mutlugun, E.; Dang, C.; Dev, K.; Gao, Y.; Tan, S.T.; Sun X.W.; Demir, H. V. (American Chemical Society, 2014)
      Flexible information displays are key elements in future optoelectronic devices. Quantum dot light-emitting diodes (QLEDs) with advantages in color quality, stability, and cost-effectiveness are emerging as a candidate for ...
    • Highly transparent, flexible, and thermally stable superhydrophobic ORMOSIL aerogel thin films 

      Budunoglu, H.; Yildirim, A.; Guler, M. O.; Bayindir, M. (American Chemical Society, 2011)
      We report preparation of highly transparent, flexible, and thermally stable superhydrophobic organically modified silica (ORMOSIL) aerogel thin films from colloidal dispersions at ambient conditions. The prepared dispersions ...
    • Robust superhydrophilic patterning of superhydrophobic ormosil surfaces for high-throughput on-chip screening applications 

      Beyazkilic, P.; Tuvshindorj, U.; Yildirim, A.; Elbuken, C.; Bayindir, M. (Royal Society of Chemistry, 2016)
      This article describes a facile method for the preparation of two-dimensionally patterned superhydrophobic hybrid coatings with controlled wettability. Superhydrophobic coatings were deposited from nanostructured organically ...
