Abstract: A Josephson junction device includes a planar arrangement including a first two-dimensional (2D) material layer, a graphene layer, and a second 2D material layer planarly arranged on a device substrate, the first 2D material layer including at least one layer of a 2D material, the graphene layer forming a first junction with the first 2D material layer, and the second 2D material layer forming a second junction with the graphene layer and including at least one layer of a 2D material. A distance between the first junction and the second junction is within a range configured to cause a Josephson effect.
