Vacancy-induced enhancement of thermal conductivity in graphene
  It is shown that the experimentally observed increase of the Young's modulus in single-layer graphene with low density of point defects leads to a noticeably enhancement of the thermal conductivity in a wide temperature range due to increasing the longitudinal and transverse phonon velocities.
