Discovery
New Record for World's Smallest Letters

Back to article | Note about images

Image showing the red and blue letters retrieved from a data cube.

Molecular holograms are fashioned with scanning tunneling microscope manipulation. When illuminated by two-dimensional electron gas, a three-dimensional holographic projection is created.

Here, two pages of information, the red and blue letters, are retrieved from a data cube verifying that the quantum nature of electron states has features smaller than anything possible or that can be used to construct elements such as letters directly with atoms. The information density limit of discrete matter identified with atomic manipulation is surpassed by showing that electrons are capable of subatomic encoding.

An electronic S formed by tiny bits of information packed more densely than its underlying atoms.

At high energies, the size of electron waves diminishes, allowing electronic features that are smaller than those created with atomic matter. The bits that this high-energy electronic S represents are packed more densely than the invisible underlying atoms.
