Self-assembled Germanium Pyramid

A self-assembled germanium "pyramid" (base 10 nanometers x 10 nanometers) on silicon. The nanoscale pyramid of germanium atoms is formed spontaneously atop a ground of silicon. Each small sphere represents an atom. This finding could help researchers develop new generations of tinier electronic devices that are governed by quantum phenomena.

This research was supported in part by the U.S. National Science Foundation.
