At Rice University, researchers have confirmed what a physicist imagined nearly two decades ago: that the geometry of matter, not merely its chemistry, can govern the flow of electricity. Nanoscale wrinkles in graphene — folds smaller than a billionth of a meter — generate electrical effects millions of times stronger than far larger systems, simply by curving sharply enough to push electrons to one side. This discovery invites a quieter revolution in how we think about designing the tools of the electronic age, suggesting that the shape of a thing may be as powerful as its substance.
