Rutgers Scientists Discover Revolutionary ‘Intercrystals’ with Potential to Transform Electronics and Quantum Computing

Researchers at Rutgers University-New Brunswick have uncovered a groundbreaking class of materials called intercrystals, which exhibit unique electronic properties that could revolutionize future technologies. Published in Nature Materials, this discovery paves the way for advancements in efficient electronics, quantum computing, and sustainable materials by harnessing atomic-level geometric control.

The team stacked two ultrathin layers of graphene—each a one-atom-thick carbon sheet—atop a layer of hexagonal boron nitride, twisting them slightly to create moiré patterns. These patterns, resembling overlapping mesh screens, dramatically altered electron behavior, enabling unprecedented control over electronic properties without changing the material’s chemical composition.

Key findings include the potential for intercrystals to develop ultra-efficient transistors, sensors, and quantum computing components. Unlike conventional crystals, intercrystals exhibit variable electronic behaviors, such as superconductivity and magnetism, when their structure is subtly adjusted. This breakthrough builds on the field of twistronics, pioneered by the same team in 2009, where twisting material layers at specific angles unlocks novel properties.

“Intercrystals give us a new handle to control electronic behavior using geometry alone,” said lead author Eva Andrei, highlighting the material’s design flexibility. Co-author Jedediah Pixley added, “You can imagine designing an entire electronic circuit where every function is controlled by tuning geometry at the atomic level.”

Intercrystals also offer environmental benefits, as they can be crafted from abundant, non-toxic elements like carbon, boron, and nitrogen, reducing reliance on rare earth metals.

This discovery marks a significant leap in material science, opening doors to atomic-level engineering of technologies. With further research, intercrystals could redefine electronics, quantum computing, and sustainable innovation. “This is just the beginning,” said Pixley, underscoring the team’s optimism for future applications.
