What is it about?
We discovered that WO₂, a simple metal oxide, has unique electrical properties. It conducts electricity extremely well and changes resistance dramatically in a magnetic field—an effect used in sensors and hard drives. This behavior is linked to its unique electronic structure and could lead to new materials for faster, more efficient electronics.

Why is it important?
We discovered that WO₂, a stable material, has special electronic properties that let electricity flow faster and more efficiently. It also reacts strongly to magnetic fields, which could help create better electronics and spin-based technology. Unlike many materials, it keeps unique topological features, making it exciting for future high-speed and energy-efficient devices.
Perspectives
This study began with the synthesis of high-quality WO₂ crystals. At first, we did not expect such a simple oxide to exhibit remarkable conductivity. However, as our collaboration with theorists progressed, we discovered that it possesses a unique electronic structure. Perhaps even the ordinary materials around you may have surprising properties.
