'Carpet' growth method produces long-sought two-dimensional quantum material

Physicists have long sought a practical two-dimensional topological insulator, a material that blocks electricity in its interior but allows conduction along its edges. This new 'carpet' growth method achieves such a material, where electrons with opposite spins travel in opposite directions along edges, minimizing energy loss. This development could advance the understanding and application of ultrathin quantum materials.
