چکیده
Nanoparticle (NP) assembly into ordered 2and 3-D superlattices has stimulated enormous recent interest as a means to create new artifi cial solids whose electronic, magnetic, and optical behaviors can be tailored by the size dependent properties of the individual NPs mediated by coupling interactions with neighboring NPs, [ 1 , 2 ] suggesting applications in a diverse range of technologies including photovoltaics, [ 3 ]

متن کاملRevealing the interfacial self-assembly pathway of large-scale, highly-ordered, nanoparticle/polymer monolayer arrays at an air/water interface.
The pathway of interfacial self-assembly of large-scale, highly ordered 2D nanoparticle/polymer monolayer or bilayer arrays from a toluene solution at an air/water interface was investigated using grazing-incidence small-angle scattering at a synchrotron source. Interfacial-assembly of the ordered nanoparticle/polymer array was found to occur through two stages: formation of an incipient random...
متن کاملA hierarchical self-assembly route to three-dimensional polymer-quantum dot photonic arrays.
We demonstrate a new hierarchical self-assembly strategy for the formation of photonic arrays containing quantum dots (QDs), in which sequential self-assembly steps introduce organization on progressively longer length scales, ranging from the nanoscale to the microscale regimes. The first step in this approach is the self-assembly of diblock copolymers to form block ionomer reverse micelles (S...
متن کاملPlanar Photonic Crystal Nanocavities with Active Quantum Nanostructures
Extreme photon localization is applicable to constructing building blocks in photonic systems and quantum information systems. A finding fact that photon localization in small space modifies the radiation process was reported in 1944 by Purcell, and advances in fabrication technology enable such structures to be constructed at optical frequencies. Many demands of building compact photonic syste...
متن کاملSpin–cavity interactions between a quantum dot molecule and a photonic crystal cavity
The integration of InAs/GaAs quantum dots into nanophotonic cavities has led to impressive demonstrations of cavity quantum electrodynamics. However, these demonstrations are primarily based on two-level excitonic systems. Efforts to couple long-lived quantum dot electron spin states with a cavity are only now succeeding. Here we report a two-spin-cavity system, achieved by embedding an InAs qu...
