Never-Before-Seen: UCLA Physicists Discover Mysterious Spiral Patterns on Solid Surfaces

Hundreds of regular patterns spontaneously emerge on a small germanium chip. A curiosity about tiny dots on a germanium wafer with metal films led to the discovery of intricate spiral patterns etched by a chemical reaction. Further experiments revealed that these patterns emerge from chemical reactions interacting with mechanical forces through a deforming catalyst. This […] Read More
