Stanford-Led Team Shows How to Store Data Using 2D Materials Instead of Silicon Chips

Stanford University researchers led a project to store data by sliding two-dimensional (2D) metal layers over each another, which could increase data density with greater energy efficiency than silicon chips.

Working with University of California, Berkeley and Texas A&M University scientists, the researchers stacked three-atom-thick layers of tungsten ditelluride and injected a tiny bit of electricity, causing each odd-numbered layer to slightly shift relative to the even-numbered layers above and below.

Another electrical injection realigned the layers, enabling generation of the 1s and 0s that make up binary data.

The researchers read the digital data stored between the shifting layers using the quantum property of Berry curvature, which means writing a 0 or 1 to the new device should use less power than current non-volatile memory.
