Previous Article
Dielectric behavior and dependence of percolation threshold on the conductivity of fillers in polymer-semiconductor composites
Polymer-semiconductor PVDF/LNO (polyvinylidene fluoride/Li doped NiO) composites were fabricated via simple blending and hot-molding technique. The dielectric behavior of such composites was studied o...

We show that oriented nanostructures from single molecules of a conducting polymer act as highly robust room-temperature single-photon sources. Individual z-oriented polymer nanostructures show high-contrast photon antibunching with a modulation depth exceeding 90%. These results suggest the feasibility of a "push-button" technology for polymer-based single-photon sources in photonic-based quantum information processing applications. ©2004 American Institute of Physics
