(Phys.org)—As biotechnology and nanotechnology continue to merge, DNA-programmable methods have emerged as a way to provide unprecedented control over the assembly of nanoparticles into complex structures, including customizable ...
Light travels at a speed of about 300,000,000 meters per second as light particles, photons, or equivalently as electromagnetic field waves. Experiments led by Hrvoje Petek, an R.K. Mellon professor in the Department of Physics ...

Nanolight sources based on resonant excitons of plasmons near a sharp metallic nanostructure have attracted great interest in optical nanoimaging. However, the resonant phenomenon only works for one type of wavelength that ...
As electronic devices and circuits shrink into the nanoscale, the ability to transfer data on a chip, at low power with little energy loss, is becoming a critical challenge. Over the past decade, squeezing light into tiny ...

(Phys.org) —A team of researchers working in Spain has developed an improved way to control surface plasmon polaritons (SPPs) in graphene. In their paper published in the journal Science, the team describes their new technique ...
Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to particular frequencies ...
