Neutral and charged excitons interplay in non-uniformly strain-engineered WS
Sviatoslav Kovalchuk, Moshe G. Harats, Guillermo López-Polín +3
We investigate the response of excitons in two-dimensional semiconductors subjected to controlled non-uniform strain fields. In our approach to non-uniform strain-engineering, a WS…
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…
