1. 1. Light emitting devices based on silicon nanostructures

   Författare :Nenad Lalic; KTH; []
   Nyckelord :;

   Sammanfattning : Although silicon is the dominant semiconductor today, lightemitting devices are currently based on compound semiconductorsdue to their direct band-gap, which promotes fast radiativerecombination. However, in nanometer-size silicon structures,carrier confinement enhances the radiative recombination,while, at the same time, suppresses diffusion to non-radiativerecombination centra, resulting in a significant increase inlight emission efficiency.
