These deformations can then couple to the low-energy electronic properties due to the sensitivity of the graphene Fermi points to symmetry-lowering deformations. Simulation results include models for constant-force springs, nanothermometers, and nanoactuators. Extended Abstract Status: Not Uploaded | ||
