Phase change memory is a type of nonvolatile memory that utilizes the capability of phase change materials (PCM) to transition between an amorphous state, where atoms are scattered, and a crystalline state, where atoms are closely aligned. This change produces a reversible electrical property that c
Whilst this field is in its infancy, phase change memory could potentially revolutionize data storage because of its high storage density, and faster read and write capabilities. But still, the complex switching mechanism and intricate fabrication methods associated with these materials have posed challenges for mass production.

Now, a group of researchers from Tohoku University has highlighted the potential use of sputtering to fabricate large-area 2D vdW tetra-chalcogenides.
“Sputtering is a widely used technique that involves depositing thin films of a material onto a substrate, enabling precise control over film thickness and composition,” explains Yi Shuang, assistant professor at Tohoku University’s Advanced Institute for Materials Research and co-author of the paper. “Our deposited NbTefilms were initially amorphous, but could be crystallized to a 2D layered crystalline phase by annealing at temperatures above 272 ºC.
