Stanford University researchers have invented a way to slide atomically-thin layers of 2D materials over one another to store more data, in less space and using less energy.
A Stanford-led team has invented a way to store data by sliding atomically thin layers of metal over one another, an approach that could pack more data into less space than silicon chips, while also using less energy. The research, led by Aaron Lindenberg, associate professor of materials science and engineering at Stanford and at the SLAC National Accelerator Laboratory, would be a significant upgrade from the type of nonvolatile memory storage that today’s computers accomplish with silicon-based technologies like flash chips.
“The arrangement of the layers becomes a method for encoding information,” Lindenberg says, creating the on-off, 1s-and-0s that store binary data. “The scientific bottom line here,” Lindenberg adds, “is that very slight adjustments to these ultrathin layers have a large influence on its functional properties. We can use that knowledge to engineer new and energy-efficient devices towards a sustainable and smart future.”
Visible Legacy Comment
Smart sensors and big data imply a massive need for memory storage. This team at Stanford has been working for several years on a technology that may allow storing data in a non-volatile memory storage but allow the speed of access needed for direct computation. They are developing phase-change memory using the state change between crystalline atomic structure and amorphous phase. The current work evolves toward using crystalline layers and changing alignment and shows promise for fast, non-volatile memory with lower energy use. The technology is available through the the Stanford Office of Technology Licensing.
