World's smallest Christmas Tree

World’s smallest “Christmas Tree” is about the size of a DNA strand, consists of 51 individual atoms.


A Physics student at Delft University of Technology creates world’s smallest Christmas tree made up of just 51 atoms from a perfect crystal lattice. The tree is exactly 4 nanometers tall, or 4 millionths of a millimeter.

The student Maura Willems for her graduation, uses high-powered microscope to build small structures, literally atom by atom, in order to study their quantum mechanical properties. Then changed each one’s position.

Willems came up with the idea of making a Christmas tree by removing 51 atoms from a perfect crystal lattice.
