Nanowires Twisted into Springs Boost Light Absorption for Nanoscale Photosensors

In the question of curly versus straight, new evidence suggests curly wins – at least in the world of nanowires. Researchers from Bilkent University, Ankara, Turkey, have shown that twisting straight nanowires into springs can increase the amount of light the wires absorb by up to 23 percent. Absorbing more light is important because one application of nanowires is turning light into electricity, for example to power tiny devices.

Dirac Cones Can Spawn a ‘Ring of Exceptional Points’

The Dirac cone, named after British physicist Paul Dirac, started as a concept in particle and high-energy physics and has recently became important in research in condensed matter physics and material science. It has since been found to describe aspects of graphene, a two dimensional form of carbon, suggesting the possibility of applications across various fields.
