Machine Learning-Based Optimization Of Chiral Photonic Nanostructures: Evolution- And Neural Network-Based Design


Chiral photonics opens new pathways to manipulate light-matter interactions and tailor the optical response of metasurfaces and -materials by nanostructuring nontrivial patterns. Chirality of matter, such as that of molecules, and light, which in the simplest case is given by the handedness of circular polarization, have attracted much attention for applications in chemistry, nanophotonics and ... » read more

Semiconductor nanochannels in metallic carbon nanotubes by thermomechanical chirality alteration


Abstract: "Carbon nanotubes have a helical structure wherein the chirality determines whether they are metallic or semiconducting. Using in situ transmission electron microscopy, we applied heating and mechanical strain to alter the local chirality and thereby control the electronic properties of individual single-wall carbon nanotubes. A transition trend toward a larger chiral angle region wa... » read more

Power/Performance Bits: Aug. 29


Colored solar panels Researchers from AMOLF, the University of Amsterdam (UvA) and the Energy Research Centre of the Netherlands (ECN) developed a technology to create efficient bright green solar panels in the hopes that a greater array of colors will prompt greater adoption among architects and builders who might see the traditional blue or black panels as an eyesore. The panels have a gr... » read more
