The authors reported on investigation of the thermal conductivity of graphene suspended across trenches in wafer. The measurements were performed using a noncontact technique based on micro-Raman spectroscopy. The amount of power dissipated in graphene and corresponding temperature rise were determined from the spectral position and integrated intensity of graphene’s mode. The extremely high thermal conductivity in the range of and phonon mean free path of near room temperature were extracted for a set of graphene flakes. The obtained results suggest graphene’s applications as thermal management material in future nanoelectronic circuits.
