However, theoretical studies revealed that phonon transport is sensitive to defects, strain, sample size and

Therefore, the development of a good thermoelectric material, useful for the majority of thermoelectric applications, should aim to maximize the efficiency η (see Equation 11). Hence, the figure of merit , and in particular the factor Z = S2σ/kt, must be as high as possible

In this respect, graphene exhibits a very high thermal conductivity, higher than 3000 W/mK [17], so that the
