Graphene has been called a wonder material for two decades, but real devices have always fallen short—until now. A new study in Nature (Domaretskiy et al., 2025, DOI: 10.1038/s41586-025-09386-0) shows how researchers achieved the highest-quality graphene ever, by placing graphite gates just 1 nanometer away. This proximity screening makes electrons move with record mobility, revealing quantum effects at magnetic fields weaker than a fridge magnet. In this short episode of Rebwar Lab, we unpack the story of graphene—from its Nobel Prize-winning discovery with Scotch tape to this 2025 breakthrough—and explore what it means for the future of quantum technology and materials science.
