Historically, people have taken a low-resolution approach to identifying where resistance comes from,\u201d says Zach Krebs, a physics graduate student at UW-Madison and co-lead author of the study. \u201cIn this study, we image how charge flows around an impurity and actually see how that impurity blocks current and causes resistance, which is something that hasn\u2019t been done before to distinguish gas-like and fluid-like electron flow.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Physicists at the University of Wisconsin-Madison have directly measured the fluid-like flow of electrons in graphene at nanometer resolution for the first time.
