Description:
An atomic resolution scanning tunneling microscope image
of the smallest observed Germanium (Ge) pyramid on a Si(001) surface. The
pyramid contains approximately 1600 atoms. The Germanium 'pyramid' is self-assembled (with a
base only 10 nanometer x 10 nanometer in size) on Silicon. The nanoscale
pyramid of germanium atoms spontaneously forms a type of quantum dot atop a ground of silicon.
Each small sphere represents an atom. It could help researchers develop new
generations of tinier electronic devices that are governed by quantum
phenomena.
