Due to the extremely low density of defects, carbon nanotubes and graphene were predicted in theory and demonstrated experimentally to possess excellent mechanical properties and can sustain relatively large strain.This gives us an opportunity to explore the impact of mechanical deformation to their physical properties.In the presentation, a systematic study of the Raman spectra of optical phonons in graphene monolayers under tunable uniaxial tensile stress will be presented.
