What to know about Discovery of 'slow' electrons in 2D material could lead to new memory device

Researchers at the University of Chicago Pritzker School of Molecular Engineering have discovered a charge-ordered state in the 2D material Fe5GeTe2 where electrons move collectively and slowly. This discovery, published in Science Advances, suggests that the material's magnetic interactions differ from theoretical predictions and could potentially be used to develop new types of memory devices.

What happened

Discovery of 'slow' electrons in 2D material could lead to new memory device Gaby Clark Scientific Editor Robert Egan Senior Editor Over the last decade, researchers have developed two-dimensional materials with fascinating quantum effects that could be…

Why it matters

Such materials have shown superconductivity—conducting electricity without energy loss—and charge orders, where electrons arrange in frozen patterns rather than moving freely in the material.

Common ground

At the University of Chicago Pritzker School of Molecular Engineering (UChicago PME), a research team discovered that one such material, Fe5GeTe2, exhibits a charge-ordered state in which electrons move collectively and unusually slowly while remaining…
