    • TiO2 thin film transistor by atomic layer deposition 

      Okyay, Ali Kemal; Oruç, Feyza B.; Çimen, Furkan; Aygün, Levent E. (SPIE, 2013)
      In this study, TiO2 films were deposited using thermal Atomic Layer Deposition (ALD) system. It is observed that asdeposited ALD TiO 2 films are amorphous and not suitable as TFT channel material. In order to use the film ...

    • ZnO based optical modulator in the visible wavelengths 

      Okyay, Ali Kemal; Aygun, Levent E.; Oruç, Feyza B. (SPIE, 2013)
      In order to demonstrate tunable absorption characteristics of ZnO, photodetection properties of ZnO based thin-film transistors are investigated. By controlling the occupancy of the trap states, the optical absorption ...
