Researchers have discovered a method to control a quantum phenomenon in advanced materials by harnessing subtle internal features like defects and lattice vibrations.

A recent study reveals that tiny imperfections and internal vibrations within a promising quantum material can be used to regulate an unusual electrical effect. This breakthrough could pave the way for smaller, faster, and more efficient energy-harvesting technologies.

An international team led by Professor Dongchen Qi from the QUT School of Chemistry and Physics, along with Professor Xiao Renshaw Wang from Nanyang Technological University in Singapore, explored the mechanism behind the nonlinear Hall effect (NLHE). Figure 1 shows self-powered electronics.

Unlike the classical Hall effect, this quantum behavior enables alternating electrical signals—such as those from wireless transmissions or ambient sources—to be directly converted into usable direct current, without the need for diodes or bulky components.

“The NLHE is a complex quantum effect in condensed matter physics where a voltage is generated perpendicular to an applied alternating current, even without a magnetic field,” explained Professor Qi.

“This allows us to transform alternating signals directly into direct current, which is essential for powering electronic devices [1]. In theory, this could lead to sensors or chips that operate without batteries by drawing energy from their surroundings.”

Material Behavior and Temperature Effects

The researchers studied a high-quality topological material known for its unique electronic properties and found that the NLHE remains stable even at room temperature. They also observed that both the magnitude and direction of the generated voltage vary with temperature.

At lower temperatures, microscopic defects within the material dominate the effect. As the temperature rises, vibrations in the crystal lattice become more influential, eventually causing the electrical signal to reverse direction.

“By understanding the internal processes within the material, we can design devices that exploit these effects,” said Professor Qi.

“That’s when quantum phenomena move beyond theory and become practical, enabling innovations such as self-powered sensors, wearable electronics, and ultra-fast components for next-generation wireless technologies.”
