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.
SLAC and Stanford partner with two Illinois universities to create the Center for Quantum Sensing and Quantum Materials, which aims to unravel mysteries associated with exotic superconductors, topological insulators and strange metals.
Cryan is an investigator with the Stanford PULSE Institute at SLAC, while Marsden is an associate professor of pediatrics and of bioengineering at Stanford.
Researchers demonstrate a new ability to drive and track electronic motion, which is crucial to understanding the role of electrons in chemical processes and how quantum coherence evolves on the shortest timescales.
The prestigious awards provide at least $2.5 million over five years in support of their work in understanding photochemical reactions and improving accelerator beams.
Understanding nature’s process could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water.
Hitting molecules with two photons of light at once set off unexpected processes that were captured in detail with SLAC’s X-ray laser. Scientists say this new approach should work for bigger and more complicated molecules, too, allowing new insights into molecular behavior.
These inexpensive photosensitizers could make solar power and chemical manufacturing more efficient. Experiments at SLAC offer insight into how they work.
Called XLEAP, the new method will provide sharp views of electrons in chemical processes that take place in billionths of a billionth of a second and drive crucial aspects of life.
