Ion association in low-polarity solvents: comparisons between theory, simulation, and experiment

Kavli Affiliate: Jos Zwanikken | Summary:The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The specific case of the restricted primitive model (charged hard spheres) is considered. Specialised simulation techniques are employed that lead to efficient sampling of the arrangements and […]

From vertical-cavities to hybrid metal/photonic-crystal nanocavities: Towards high-efficiency nanolasers

Kavli Affiliate: Axel Scherer | Summary:We provide a numerical study showing that a bottom reflector is indispensable to achieve unidirectional emission from a photonic-crystal (PhC) nanolaser. First, we study a PhC slab nanocavity suspended over a flat mirror formed by a dielectric or metal substrate. We find that the laser’s vertical emission can be enhanced […]
