    • Low dark current diffusion limited planar type InGaAs photodetectors 

      Dolaş, M. Halit; Ateşal, Okan; Çalışkan, M. Deniz; Bek, A.; Özbay, Ekmel (SPIE, 2019)
      In this work, we design and produce 1280x1024 format InGaAs based planar type detectors with 15μm pixel pitch. We have obtained diffusion current limited low dark current (~10fA) and high responsivity (1.08A/W at 1.55μm) ...
    • Solar-blind AlxGa1-xN-based avalanche photodiodes 

      Tut, T.; Butun, S.; Butun, B.; Gokkavas, M.; Yu, H. B.; Özbay, Ekmel (American Institute of Physics, 2005)
      We report the Metalorganic Chemical Vapor Deposition (MOCVD) growth, fabrication, and characterization of solar blind AlxGa1-xN/GaN-based avalanche photodiodes. The photocurrent voltage characteristics indicate a reproducible ...
