  • As well as helping us to understand the mechanisms underlying the evolution of beauty in nature, Dufresne adds that his research has the 'potential for finding a new class of photonic (light-emitting) materials, based on disordered, instead of periodic structures.'

  • The nanometer-sized gizmo could provide a key tool for researchers trying to develop a new type of microchip technology called "plasmonics" that mixes electronics and optics.
  • The channel in Zhang's device measures as little as 40 nanometers wide by 5 nanometers high, far smaller than the roughly 250-nanometer diameter of a conventional laser of a similar wavelength.
  • Some physicists and engineers are hoping to build nanocircuits that manipulate plasmonics to marry high-speed electronics and high-speed optics.

    Nonradiative resonant energy transfer in optimized QD-QW systems may provide a solar energy conversion approach with a viable tradeoff with the bottlenecks of charge carrier generation and/or transport to/in electrodes faced by excitonic solar cells.

    Carrier multiplication (CM) is a process in which absorption of a single photon produces not just one but multiple electron-hole pairs. This effect is a potential enabler of next-generation, high-efficiency photovoltaic and photocatalytic systems.
