(PhysOrg.com) -- A team of scientists at MIT have discovered a
previously unknown phenomenon that can cause powerful waves of energy
to shoot through minuscule wires known as carbon nanotubes. The
discovery could lead to a new way of producing electricity, the
researchers say.
The phenomenon, described as thermopower waves, “opens up a new area of
energy research, which is rare,” says Michael Strano, MIT’s Charles and
Hilda Roddey Associate Professor of Chemical Engineering, who was the
senior author of a paper describing the new findings that appeared in Nature Materials on March 7. The lead author was Wonjoon Choi, a doctoral student in mechanical engineering.
Like a collection of flotsam propelled along the surface by waves
traveling across the ocean, it turns out that a thermal wave — a moving
pulse of heat — traveling along a microscopic wire can drive electrons
along, creating an electrical current...
