    • Amyloid-like peptide nanofiber templated titania nanostructures as dye sensitized solar cell anodic materials 

      Acar, H.; Garifullin, R.; Aygun, L. E.; Okyay, Ali Kemal; Güler, Mustafa O. (Royal Society of Chemistry, 2013)
      One-dimensional titania nanostructures can serve as a support for light absorbing molecules and result in an improvement in the short circuit current (Jsc) and open circuit voltage (Voc) as a nanostructured and high-surface-area ...
    • Au/TiO2 nanorod-based Schottky-type UV photodetectors 

      Karaagac, H.; Aygun, L. E.; Parlak, M.; Ghaffari, M.; Bıyıklı, Necmi; Okyay, Ali Kemal (Wiley, 2012-10-12)
      TiO2 nanorods (NRs) were synthesized on fluorine-doped tin oxide (FTO) pre-coated glass substrates using hydrothermal growth technique. Scanning electron microscopy studies have revealed the formation of vertically-aligned ...
    • A baseball-bat-like CdTe/TiO2 nanorods-based heterojunction core–shell solar cell 

      Karaagac, H.; Parlak, M.; Aygun, L. E.; Ghaffari, M.; Bıyıklı, Necmi; Okyay, Ali Kemal (Elsevier, 2013)
      Rutile TiO2 nanorods on fluorine-doped thin oxide glass substrates via the hydrothermal technique were synthesized and decorated with a sputtered CdTe layer to fabricate a core-shell type n-TiO2/p-CdTe solar cell. Absorbance ...
    • Dynamic control of photoresponse in ZnO-based thin-film transistors in the visible spectrum 

      Aygun, L. E.; Oruc, F. B.; Atar, F. B.; Okyay, Ali Kemal (IEEE, 2013-04)
      We present ZnO-channel thin-film transistors with actively tunable photocurrent in the visible spectrum, although ZnO band edge is in the ultraviolet. ZnO channel is deposited by atomic layer deposition technique at a low ...
    • Low temperature atomic layer deposited ZnO photo thin film transistors 

      Oruc, F. B.; Aygun, L. E.; Donmez, I.; Bıyıklı, Necmi; Okyay, Ali Kemal; Yu, H. Y. (AVS Science and Technology Society, 2014)
      ZnO thin film transistors (TFTs) are fabricated on Si substrates using atomic layer deposition technique. The growth temperature of ZnO channel layers are selected as 80, 100, 120, 130, and 250°C. Material characteristics ...
