Direct observation of Fermi surface of heavy electron, and new solid electrolyte for batteries

SPring-8 has emitted two excellent technologies recently. SPring-8 = large-scale synchrotron radiation facility located in Hyōgo Prefecture, Japan.
1) World’s first direct observation of actual formation of the Fermi surface of the heavy electron
The Fermi surface of the heavy electron was observed when the researcher team selectively observed specific electron orbitals in a “resonant angle-resolved photoemission spectroscopy” experiment, which used soft x-ray radiation in SPring-8. The successful observation provides a clue to the attractive superconducting mechanism coexisting with magnetism. The study result will be online published on Physical Review Letters, May 27, 2009/05/28.

2) New solid electrolyte for batteries
The solid electrolyte developed has extremely high ion conductivity even at room temperature, and is stable and highly heat resistive at atmospheric pressure. It will accelerate the development of high performance batteries. The battery user will be released from dangerous accident (e.g., explosion) inherent to the liquid electrolyte thus far used.
The study result was online published on Nature Materials, May 17, 2009
