Graphene Sandwich Accelerates Electrons ⚡ экспресс
Original: "Quantum Hall Effect at 0.002T"
Two graphene sheets with an insulating layer in between smooth out each other's atomic imperfections, letting electrons zip through with barely any resistance.

A one-atom-thick graphene sheet—and a 'carpet' of a second such sheet above it. This setup eliminates electrical 'potholes' that trip up electrons. The result: record mobility, with quantum resistance jumps appearing in a fridge magnet's field. A step toward future electronics.
🎯 Electrons in the graphene sandwich behave as if each split into three parts—this quantum phenomenon opens the door to particles with exotic properties.
