At the nanoscale level, electrons can push atoms around

By 9 May 2010

In a paper published in Science this week, a group of researchers showed that an electrical current run through a nanoscale metal wire┬ácan actually cause some of the wire’s atoms to flow backwards against the current. The effect is larger for smaller particles, and is yet another issue scientists will have to take into account when making tiny electronic devices. Scientists had previously …
