    • Descending Infrared Transmission Spectra of CdZnTe Substrates Due to Surface Roughness 

      Selvig, Espen; Kongshaug, Kjell Ove; Haakenaasen, Randi; Lorentzen, Torgeir; Brudevoll, Trond (2019-06-11)
      (111)B-oriented Cd0.96Zn0.04Te substrates with rough surfaces have been found to have infrared (IR) transmission spectra which decrease rapidly in intensity as the photon energy increases. The rough surfaces were produced ...
    • Elektrooptiske begrensere 

      Stenersen, Knut; Villanger, Asta Storebø; Brudevoll, Trond; Ajer, Halvor (2002)
      A description is given of physical mechanisms and promising materials which can be utilized in optical power limiting devices. The discussion is focussed on use of such limiters for protection of military electro-optic ...
    • Modeling of a back-illuminated HgCdTe MWIR avalanche photodiode with alloy gradients 

      Storebø, Asta Katrine; Brudevoll, Trond (2015)
      We present results from 2D Monte Carlo simulations of a mid-wave infrared (MWIR) back-illuminated planar n-on-p HgCdTe electron-initiated avalanche photodiode (e- APD). The main objective of this work has been to study the ...
    • Simulation of infrared avalanche photodiodes from first principles 

      Storebø, Asta Katrine; Goldar, Dara; Brudevoll, Trond (2017)
      The present article deals with device physics and modeling of an Hg0.28Cd0.72Te wide-area electron-initiated avalanche photodiode, with main input data extracted from first principles electronic structure codes. Due to the ...
