Abstract

InAs/ZnSe core/shell nanoparticles (NP) were self-assembled on GaAs substrates using different organic molecules of varying length and properties as linkers. The molecules provide control over the coupling and tunneling properties between the substrate and the nanocrystals. By coadsorbing of gold NP on the GaAs substrate, enhancement of the photoluminescence from the InAs NP was achieved. The enhancement factor was found to depend on the properties of the organic linkers.
