Internal Quantum Efficiency Enhancement of Silicon Nanocrystals Using Doublelayer Au Film Surface-Plasmon Waveguide

Using double layer Au film surface-plasmon waveguides, Purcell factor can be improved dramatically. Under the same background loss, more significant enhancement in internal quantum efficiency of silicon nanocrystals can be obtained compared with the monolayer structure.
