At the frontier where physics meets engineering ambition, researchers at POSTECH in South Korea have resolved a paradox that has quietly constrained the semiconductor industry for years: the thinner a chip's channel, the harder it becomes for current to enter it. By selectively thickening only the points where electrons cross from metal into material, the team found a way to honor both demands at once — suppressing leakage without strangling flow. It is the kind of solution that does not defeat a constraint so much as sidestep it with precision, and its implications reach toward the three-dime
