Super-Efficient Exciton Funneling in Layer-by-Layer Semiconductor Nanocrystal StructuresOur results on energy transfer in layer-by-layer assembled semiconductor nanocrystal structures relied on the help of and fruitful discussions with many colleagues. We thank all of them, in particular Dmitry Koktysh, Nikolai Gaponik, Alexey Shavel, Alexander Eychmüller, Stefan Schietinger, Werner Stadler, and Anna Helfrich. Financial support has been provided by the Deutsche Forschungsgemeinschaft through the Gottfried-Wilhelm-Leibniz-Preis.
