Abstract:
We report the 1D linear, 2D square, 2D honeycomb, and 3D topo-epitaxy long-range superstructures of oriented attached PbSe NCs. In particular, we discovered novel 1D linear and 3D superstructures, which implied different formation mechanisms compared with the PbSe superstructures previously reported. Our study not only demonstrates stronger design capability for oriented-attached PbSe superstructures, but also reveals important information about the interfacial behavior of the PbSe NCs during the self-assembly.
