    • Graphene on Silicon-Nitride Photodetector 

      Moein, Tania; Gailevicius, Darius; Katkus, Tomas; Ng, Soon Hock; Lundgaard, Stefan; Varapnickas, Simonas; Moss, David J.; Kurt, Hamza; Mizeikis, Vygantas; Staliunas, Kestutis; Malinauskas, Mangirdas (SPIE, 2019-12)
      Even though graphene is a gapless material, it demonstrates strong interband absorption from a broad range of wavelengths between VIS and NIR. Recent photocurrent graphene-based detectors demonstrated strong photoresponse ...
    • Optically-Thin Broadband Graphene-Membrane Photodetector 

      Moein, Tania; Gailevicius, Darius; Katkus, Tomas; Ng, Soon Hock; Lundgaard, Stefan; Moss, David J.; Kurt, Hamza; Mizeikis, Vygantas; Staliunas, Kestutis; Malinauskas, Mangirdas; Juodkazis, Saulius (MDPI AG, 2020-02)
      A broadband graphene-on-Si3N4-membrane photodetector for the visible-IR spectral range is realised by simple lithography and deposition techniques. Photo-current is produced upon illumination due to presence of the build-in ...
