Abstract: We carried out micro-Raman spectroscopy of graphene layers over thetemperature range from approximately 80 K to 370 K. The number of layers wasindependently confirmed by the quantum Hall measurements and atomic forcemicroscopy. The measured values of the temperature coefficients for the G and2D-band frequencies of the single-layer graphene are -0.016 1-cm K and -0.0341-cm K, respectively. The G peak temperature coefficient of the bi-layergraphene and bulk graphite are -0.015 1-cm K and -0.011 1-cm K,respectively.
