Estimation of Young's Modulus of Graphene by Raman Spectroscopy
Jae-Ung Lee, Duhee Yoon, Hyeonsik Cheong
The Young's modulus of graphene is estimated by measuring the strain applied by a pressure difference across graphene membranes using Raman spectroscopy. The strain induced on pres…
Negative Thermal Expansion Coefficient of Graphene Measured by Raman Spectroscopy
Duhee Yoon, Young-Woo Son, Heonsik Cheong
The thermal expansion coefficient (TEC) of single-layer graphene is estimated with temperature-dependent Raman spectroscopy in the temperature range between 200 and 400 K. It is fo…
Thermal conductivity of suspended pristine graphene measured by Raman spectroscopy
Jae-Ung Lee, Duhee Yoon, Hakseong Kim +2
The thermal conductivity of suspended single-layer graphene was measured as a function of temperature using Raman scattering spectroscopy on clean samples prepared directly on a pr…
