Understanding strontium titanate’s odd behavior will aid efforts to develop materials that conduct electricity with 100 percent efficiency at higher temperatures.
Research conducted at the atomic scale could help explain how electric currents move efficiently through hybrid perovskites, promising materials for solar cells.
These stripes of electron spin and charge are exciting because of their possible link to a phenomenon that could transform society by making electrical transmission nearly 100 percent efficient.
Kumar’s work, carried out in part at SSRL, explains how memristors work – a new class of electronic devices with applications in next-generation information storage and computing.
Tripling the energy and refining the shape of optical laser pulses at LCLS’s Matter in Extreme Conditions instrument allows researchers to recreate higher-pressure conditions and explore unsolved questions relevant to fusion energy, plasma physics and materials science.
SLAC’s ultrafast “electron camera” reveals unusual atomic motions that could be crucial for the efficiency of next-generation perovskite solar cells.
Extraordinarily precise measurements -- within millionths of a billionth of a second and a billionth of a hair's breadth -- show this ‘electron-phonon coupling’ can be far stronger than predicted, and could potentially play a role in unconventional superconductivity.
Propagating “charge density wave” fluctuations are seen in superconducting copper oxides for the first time.
Understanding how a material’s electrons interact with vibrations of its nuclear lattice could help design and control novel materials, from solar cells to high-temperature superconductors.
The award honors his work on a world-class experimental station at SLAC's Stanford Synchrotron Radiation Lightsource.
