Science and Technology, Quantum Daisy

Quantum daisy. Twelve cobalt atoms arranged in a circle on a surface of copper produce a daisy-like pattern from the interference of electron wave. This image was made with a one-of-a-kind instrument

that, acting autonomously, picks up and places individual atoms anywhere on a surface. NIST scientists are studying the quantum properties of different atom arrangements to help improve the design and fabrication of nanoscale devices
