The ability to precisely manipulate individual charge carriers is a cornerstone for single-electron transistors and for electronic devices of the future, including solid-state quantum bits (qubits). Quantum dots (QDs) are at the heart of these devices. In a recent Nano Letters paper, researchers at Delft University of Technology (TU Delft) present the first mechanically-tunable monolayer graphene QD whose electronic properties can be modified by in-plane nanometer displacements.
