Superconductivity of augmented C60 molecules
Researchers Find Way to Make 'Buckyballs'
Conduct Electricity at Higher Temperatures
WASHINGTON -- Researchers have found a way to make carbon
"buckyballs" conduct electricity with extreme efficiency at warmer
temperatures, a finding that could lead to new types of ultrafast
Scientists at Lucent Technologies ' Bell Labs report that they
achieved superconductivity -- electricity flowing without resistance
-- with carbon-60 at a temperature of about minus-249 degrees by
combining the carbon molecules with two chemical compounds,
chloroform and bromoform.
This mixture substantially raises the temperature at which carbon-60
can achieve superconductivity. Previous experiments by the Bell Labs
group had shown that carbon-60 -- known as fullerenes or buckyballs
after Buckminster Fuller -- when mixed with other chemicals could
superconduct at minus-366 degrees F.
A report on the research appears Friday in the journal Science.
