Abstract

We carried out micro-Raman spectroscopy of graphene layers over the temperature range from approximately 80 K to 370 K. The number of layers was independently confirmed by the quantum Hall measurements and atomic force microscopy. The measured values of the temperature coefficients for the G and 2D-band frequencies of the single-layer graphene are -0.016 1/(cm K) and -0.034 1/(cm K), respectively. The G peak temperature coefficient of the bi-layer graphene and bulk graphite are -0.015 1/(cm K) and -0.011 1/(cm K), respectively.
