Researchers have shown that they can tune the strain in graphene suspended like drumheads over microscopic holes in a substrate of silicon oxide using the tip of an advanced scanning probe microscope and a conducting plate below the substrate. Tuning the strain enabled the group to create areas in the graphene where electrons behaved as though they were confined to quantum dots.
