Abstract
We report piezoresistance measurements of uniaxially strained graphene ribbons obtained by performing in-situ nanoindentation experiments on suspended graphene devices with simultaneous electrical measurements. We find the Young's modulus of graphene to be ~335 N/m, which is consistent with previous reports. We measure the gauge factor of graphene ribbons to be ~2, a value close to that predicted by a tight binding model.
