Data Storage Breakthrough Could Store the Library of Congress on a Dust Mite

The densest data storage device ever invented.
Jul 18, 2016
Using this new data storage technique, you could fit the entire Library of Congress on a cube smaller than a dust mite—or the size of George Washington's pupil on a one dollar bill.

Abstract
The advent of devices based on single dopants, such as the single-atom transistor1, the single-spin magnetometer2, 3 and the single-atom memory4, has motivated the quest for strategies that permit the control of matter with atomic precision. Manipulation of individual atoms by low-temperature scanning tunnelling microscopy5 provides ways to store data in atoms, encoded either into their charge state6, 7, magnetization state8, 9, 10 or lattice position11. A clear challenge now is the controlled integration of these individual functional atoms into extended, scalable atomic circuits. Here, we present a robust digital atomic-scale memory of up to 1 kilobyte (8,000 bits) using an array of individual surface vacancies in a chlorine-terminated Cu(100) surface. The memory can be read and rewritten automatically by means of atomic-scale markers and offers an areal density of 502 terabits per square inch, outperforming state-of-the-art hard disk drives by three orders of magnitude. Furthermore, the chlorine vacancies are found to be stable at temperatures up to 77 K, offering the potential for expanding large-scale atomic assembly towards ambient conditions.
