A research team from the University of Wollongong's (UOW) Institute for Superconducting and Electronic Materials (ISEM) has addressed a 40-year-old quantum puzzle, unlocking a new pathway to creating next-generation electronic devices that operate without losing energy or wasting electricity.

Published in Advanced Materials, is the work of UOW researchers led by Distinguished Professor Xiaolin Wang and Dr. M Nadeem, with Ph.D. candidate Syeda Amina Shabbir and Dr. Frank Fei Yun.

It introduces a new design concept to realize the elusive and highly sought-after quantum anomalous Hall (QAH) effect.

The field of quantum materials could cut global energy consumption and transform everyday life for people around the world.

Using a technique called entropy engineering, the team tailored the quantum behavior of a 1-atom-thick magnetic material by mixing four types of metal atoms. This random atomic arrangement reshaped the material's electronic structure, opening a topological bandgap that allows electricity to flow perfectly along its edges, without interference or energy loss.

This is a kind of "superhighway" for electricity, and it's a building block for future quantum computers and ultra-efficient electronics.

The method the UOW team used鈥攃hanging the "entropy" or randomness inside the material鈥攇ives scientists a new tool to design even better quantum materials in the future.

"This is a significant step toward practical quantum devices that are energy-efficient, scalable and resilient," said Professor Wang. "Our method opens a new avenue to design 2D quantum materials with robust topological properties."

The breakthrough has broad potential applications鈥攆rom phones and computers that don't overheat, to quantum computers, faster medical imaging, and energy systems that retain power for weeks. It also advances a class of materials first conceptualized and pioneered by Professor Wang known as spin-gapless semiconductors.

Dr. Nadeem, who led the theoretical modeling, said, "The entropy-driven design not only reshaped the electronic bands, but also opened a stable gap that ensures edge-state conduction, which is essential for real-world quantum applications."

Professor Wang emphasized the significance of the discovery, stating, "This represents a significant theoretical advancement toward the development of emerging quantum devices that are energy-efficient, scalable, and resilient. We are creating a new class of quantum materials that open fresh horizons for novel quantum physics and devices."
