"Unveiling Resistance-Free Electron Channels at Chiral Interfaces"
Scientists at Lawrence Berkeley National Laboratory have developed a new technique to create resistance-free electron channels by visualizing and controlling chiral interface states in a quantum anomalous Hall insulator made from twisted monolayer-bilayer graphene. This exotic quantum phenomenon could advance quantum computing and energy-efficient electronics, with potential applications in tunable networks of electron channels and low-power magnetic memory devices. The researchers' work, published in Nature Physics, provides a significant step forward in understanding and manipulating these unique electron behaviors in quantum materials.
