    • GaN/AlGaN-based UV photodetectors with performances exceeding the PMTS 

      Tut, Turgut (Bilkent University, 2008)
      The recent developments in high Al-content AlxGa1−xN material growth technology made it possible to fabricate high performance solar-blind photodetectors operating in the ultraviolet (UV) spectral region with improved receiver ...
    • High performance AlxGa1-xN-based avalanche photodiodes 

      Tut, T.; Butun, B.; Gokkavas, M.; Özbay, Ekmel (Elsevier BV, 2007-10)
      We report high performance solar-blind photodetectors with reproducible avalanche gain as high as 820 under ultraviolet illumination. The solar-blind photodetectors have a sharp cut-off around 276 nm. We improved the ...
