    • Computational modeling of quantum-confined impact ionization in Si nanocrystals embedded in SiO2 

      Sevik, C.; Bulutay, C. (2007)
      Injected carriers from the contacts to delocalized bulk states of the oxide matrix via Fowler-Nordheim tunneling can give rise to quantum-confined impact ionization (QCII) of the nanocrystal (NC) valence electrons. This ...
    • Harmonic enhancement of Gunn oscillations in GaN 

      Sevik, Cem; Yılmaz, Dündar E.; Bulutay, Ceyhun (American Institute of Physics, 2005)
      High field transport in wide bandgap semiconductors like GaN is of great technological importance. The negative differential mobility regime at high fields, under suitable conditions, can lead to millimeter-wave Gunn ...
    • High field transport phenomena in wide bandgap semiconductors 

      Sevik, Cem (Bilkent University, 2003)
      The Ensemble Monte Carlo (EMC) method is widely used in the field of computational electronics related to the simulation of the state of the art devices. Using this technique our specific intention is to scrutinize the ...
    • Simulation of millimeter-wave gunn oscillations in gallium nitride 

      Sevik, C.; Bulutay, C. (2004)
      High field transport in wide bandgap semiconductors like GaN is of great technological importance. The negative differential mobility regime at high fields, under suitable conditions, can lead to millimeterwave Gunn ...
