These fleeting disruptions, seen for the first time in lead hybrid perovskites, may help explain why these materials are exceptionally good at turning sunlight into electrical current in solar cells.
The study, done on a mild-mannered relative of the virus that causes COVID-19, paves the way for seeing more clearly how spike proteins initiate infections, with an eye to preventing and treating them.
The results, which show that ultrafast atomic motions are the first step in forming a magnetic state, could lead to faster and more efficient data storage devices.
Knowledge of physics and a love of challenges fuel May Ling Ng’s quest for nanometer perfection in the smooth surfaces of mirrors used at SLAC’s X-ray laser.
A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell.
Presented by Yijin Liu. In batteries, energy is stored in tiny particles within the electrodes that individually breathe in and out and chemically evolve as the battery is charged and discharged.
Just as pressing a guitar string produces a higher pitch, sending laser light through a material can shift it to higher energies and higher frequencies. Now scientists have discovered how to use this phenomenon to explore quantum materials in a...
