In this work, we shall demonstrate theoretically that, for certain energy ranges, the electron‐transport properties of a bilayer‐graphene‐flake (BGF)‐based system may be strongly modified by small variations of the interlayer spacing. On the other hand, the interlayer spacing variation may be yielded by a vibrational mode in the terahertz region. Thus, a BGF‐based terahertz switch is proposed. Potential applications include terahertz pulse generators, digital electronics, and logic devices.
