Scientists make first room-temperature superconductor (UPDATE)

Posted on Friday, March 21 2008 @ 03:00:30 CET by

A Canadian-German team has fabricated a new superconducting material out of a silicon-hydrogen compound that doesn't need super-cooling. The new material is super-compressed and has superconductivity at room temperature:
Instead of super-cooling the material, as is necessary for conventional superconductors, the new material is instead super-compressed. The researchers claim that the new material could sidestep the cooling requirement, thereby enabling superconducting wires that work at room temperature.

"If you put hydrogen compounds under enough pressure, you can get superconductivity," said professor John Tse of the University of Saskatchewan. "These new superconductors can be operated at higher temperatures, perhaps without a refrigerant."

He performed the theoretical work with doctoral candidate Yansun Yao. The experimental confirmation was performed by researcher Mikhail Eremets at the Max Plank Institute in Germany.

The new family of superconductors are based on a hydrogen compound called "silane," which is the silicon analog of methane--combining a single silicon atom with four hydrogen atoms to form a molecular hydride. (Methane is a single carbon atom with four hydrogens).

Researchers have speculated for years that hydrogen under enough pressure would superconduct at room temperature, but have been unable to achieve the necessary conditions (hydrogen is the most difficult element to compress). The Canadian and German researchers attributed their success to adding hydrogen to a compound with silicon that reduced the amount of compression needed to achieve superconductivity.
Turns out this was a bit too good to be true. EE Times has updated their article and so far this superconductor only exists in theory.

Do silanes form hybrid orbitals like hydrocarbons? Not sure if that is germane, the thought just struck me, so I asked.
