WebNov 26, 2024 · The high charge carrier mobility attained at room temperature in graphene encapsulated in hexagonal boron nitride (hBN) (1) has enabled the observation of ballistic transport over macroscopic distances (2−4) holding the promise for the development of room-temperature electrical equivalents of optical circuits. WebWe investigate the electronic properties of ultrathin hexagonal boron nitride (h-BN) crystalline layers with different conducting materials (graphite, graphene, and gold) on either side of the barrier layer. The tunnel current depends exponentially on the number of h-BN atomic layers, down to a monolayer thickness.
