MIT physicists have discovered a new property in magic-angle graphene, enabling the superconductivity to be turned on and off with an electric pulse. Magic-angle graphene refers to a specific form of graphene that creates a slightly offset moiré pattern, offering unique electronic behaviors. The discovery could lead to energy-efficient superconducting transistors for neuromorphic devices. Researchers are exploring how certain electronic properties emerge from the twisting and layering of two-dimensional materials under the field of twistronics.
