A Simple Route to Tunable Two-Dimensional Arrays of Quantum Dots

摘要

We have demonstrated a simple, robust, and flexible procedure to generate 2D arrays of quantum dots. These periodic arrays can be scaled from 100 nm to 5 μm with relative ease: the NSL masks can be replicated, so scale-up to macroscopic areas is feasible. Indeed, centimeter-sized, perfect arrays have been reported. These periodic luminescent structures should exhibit photonic bandgaps. Additionally they provide a well-defined platform for studies of energy transfer between nanocrystals.
