(Phys.org)—A small team of researchers at IBM Research–Zürich, has found a new way to measure the friction involved when two planes of highly ordered pyrolytic graphite (HOPG) are moved against one another. In their paper published in the journal Science, the team explains how their technique works and what they found when using it with some graphite materials. Kenneth Liechti of the University of Texas offers a Perspective piece on the work done by the team in the same journal issue and suggests ways in which the new technique might prove useful for the design and reliability of nano and micro electrical systems.
