While making materials samples to pursue their own research goals, scientists at the U.S. Department of Energy’s Ames Laboratory discovered that an unwanted byproduct of their experiments was an extremely high-quality and difficult-to-obtain substance sought after by scientists researching layered materials.
States of local broken symmetry at high temperature—observed in several materials, including one with a metal-insulator transition, an iron-based superconductor, and an insulating mineral part of the Earth’s upper mantle—may enable the technologically relevant properties arising at much-lower temperature.
The American Physical Society has selected physicist Ivan Bozovic of the U.S. Department of Energy’s Brookhaven National Laboratory as a co-recipient of the 2021 James C. McGroddy Prize for New Materials. Bozovic and his collaborators were recognized “For pioneering the atomic-layer-by-layer synthesis of new metastable complex-oxide materials, and the discovery of resulting novel phenomena.”
A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a technique that could lead to new electronic materials that surpass the limitations imposed by Moore’s Law.
It represents an entirely new type of ground state for transition metal oxides, and opens new directions for experiments and theoretical studies of how superconductivity arises and how it can be optimized in this system and possibly in other compounds.
