Tailoring the thermal expansion of graphene via controlled defect creation
Guillermo López-Polín, Maria Ortega, J. G. Vilhena +5
Contrary to most materials, graphene exhibits a negative thermal expansion coefficient (TEC), i.e it contracts when heated. This contraction is due to the thermal excitation of low…
Strain dependent elastic modulus of graphene
Guillermo López-Polín, Miriam Jaafar, Francisco Guinea +3
Indentation experiments on graphene membranes pre-stressed by hydrostatic pressure show an increase in effective elastic modulus from 300 N/m in non pressurized membranes to 700 N/…
Stiffening graphene by controlled defect creation
Guillermo López-Polín, Cristina Gómez-Navarro, Vincenzo Parente +4
Graphene extraordinary strength, stiffness and lightness have generated great expectations towards its application in flexible electronics and as mechanical reinforcement agent. Ho…
