Electrons in semiconductor distribute on surface in fractal patterns
In this image, electrons in a semiconductor are distributed across the surface of the material in complex, fractal-like patterns. These shapes are visible in this electron map, where the colors red, orange and yellow indicate areas on the surface of the semiconductor where electrons are most likely to be found at a given point in time. A fractal-like probability map of electrons is superimposed on the atomic crystal structure of the material, imaged at the same time.
