Computer simulations by SLAC physicists show how light pulses can create channels that conduct electricity with no resistance in some atomically thin semiconductors.
Stanford postdoctoral researcher Stephen Dongmin Kang, left, demonstrates how he works at a modular glovebox workstation while Stanford postdoc Jungjin Park works at a neighboring computer in a SLAC battery lab.
In this illustration, the pairs of red spheres are escaping oxygen atoms and purple spheres are metal ions. This new understanding could lead to new ways to minimize the problem and improve battery performance.
The sun rises over the Science and User Support Building (SUSB) at the entrance to SLAC National Accelerator Laboratory. Stanford's iconic Hoover Tower is just visible in the distance.
