dc.description.abstract | While thermally cycling monolayer, bilayer and trilayer graphene between 5 K and 300 K Raman spectroscopy has
shown that cooling to 5 K induces a strain in these graphene flakes of −0.081 ± 0.003%. This strain was used to
measure the graphene thermal expansion coefficient (TEC) which was found to be (−3.2±0.2)×10−6 K
−1
for monolayers, (−3.4 ± 0.4) × 10−6 K
−1
for bilayers and (−3.8 ± 0.6) × 10−6 K
−1
for trilayers at room temperature. The
TEC showed a similar temperature dependence across all graphene thicknesses and was found to be in good agreement with theoretical predictions. This study thus represents the first measurement of the TEC of bilayer and trilayer
graphene. Modification of graphene flakes of all thicknesses with various electrical contact designs was found to have
no significant impact on the resulting strain, and thus the TEC, compared to the pristine graphene. | en_GB |
