Transistors have been shrinking for decades, and the next frontier requires semiconductors just one atom thick. The challenge has been that the methods capable of producing these materials at industrial scale tend to compromise quality.
Yale Engineering's Cong Su and collaborators found a remarkably simple fix. By pre-treating chemical ingredients with acid, the team anchored them to the surface during growth – eliminating the defective, patchy layers that have long plagued scalable production. The result is record-quality atomically thin materials with direct implications for faster, more efficient electronic and quantum devices.
