Quantum dot devices of various sizes are carved from graphene. Large-scale quantum dots (>100 nm) are found to behave as conventional single-electron transistors. On the other hand, for smaller quantum dots quantum confinement is shown to have an effect. Moorfield ‘soft etching’ technology is used to prepare substrates for mechanical exfoliation of graphene, and for etching graphene into quantum dot structures.
