  • Atomic layer deposition synthesized TiOx thin films and their application as microbolometer active materials 
    Tanrikulu, Mahmud Yusuf; Rasouli, Hamid Reza; Ghaffari, Mohammad; Topalli, Kagan; Okyay, Ali Kemal (JOURNAL OF VACUUM SCIENCE & TECHNOLOGY A / A V S AMER INST PHYSICS, 2016-05)
    This paper demonstrates the possible usage of TiOx thin films synthesized by atomic layer deposition as a microbolometer active material. Thin film electrical resistance is investigated as a function of thermal annealing. ...
  • Atomic-layer-deposited zinc oxide as tunable uncooled infrared microbolometer material 
    Battal, Enes; Bolat, Sami; Tanrikulu, Mahmud Yusuf; Okyay, Ali Kemal; Akin, Tayfun (PHYSICA STATUS SOLIDI A-APPLICATIONS AND MATERIALS SCIENCE / WILEY-V C H VERLAG GMBH, 2014-11)
    ZnO is an attractive material for both electrical and optical applications due to its wide bandgap of 3.37eV and tunable electrical properties. Here, we investigate the application potential of atomic-layer-deposited ZnO ...
  • Digitally alloyed ZnO and TiO2 thin film thermistors by atomic layer deposition for uncooled microbolometer applications 
    Tilkioglu, Bilge T.; Bolat, Sami; Tanrikulu, Mahmud Yusuf; Okyay, Ali Kemal (JOURNAL OF VACUUM SCIENCE & TECHNOLOGY A / A V S AMER INST PHYSICS, 2017-03)
    The authors demonstrate the digital alloying of ZnO and TiO2 via atomic layer deposition method to be utilized as the active material of uncooled microbolometers. Depositions are carried out at 200 degrees C. Crystallinity ...
  • LWIR all-atomic layer deposition ZnO bilayer microbolometer for thermal imaging 
    Poyraz, Muhammet; Gorgulu, Kazim; Sisman, Zulkarneyn; Tanrikulu, Mahmud Yusuf; Okyay, Ali Kemal (OPTICAL ENGINEERING / SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS, 2017-03)
    We propose an all-ZnO bilayer microbolometer, operating in the long-wave infrared regime that can be implemented by consecutive atomic layer deposition growth steps. Bilayer design of the bolometer provides very high ...
