Abstract
Processes for shaping one- and two-dimensional nanomaterials, and thereby inducing local strains therein preferably to control one or more of their material properties. The processes include providing a substrate comprising a three-dimensional surface feature thereon, locating a nanomaterial on the substrate and over the surface feature, and directing a laser beam toward the nanomaterial such that the nanomaterial experiences laser shock pressure sufficient to deform the nanomaterial to conform at least partially to the shape of the surface feature and adhere to the surface feature either directly or via an intermediate layer therebetween.

A process comprising:
- providing a substrate comprising a three-dimensional surface feature thereon formed;
- locating a nanomaterial on the substrate and over the surface feature
- directing a laser beam toward the nanomaterial such that the nanomaterial experiences laser shock pressure sufficient to deform the nanomaterial to conform at least partially to the shape of the surface feature and adhere to the surface feature either directly or via an intermediate layer therebetween;
- and
- controlling the deformation of the nanomaterial to tunably modify a material property of the nanomaterial.
A process comprising:
- providing a substrate comprising a three-dimensional surface feature thereon;
- locating a one-dimensional nanomaterial on the substrate and over the surface feature;
- and
- directing a laser beam toward the nanomaterial such that the nanomaterial experiences laser shock pressure sufficient to deform the nanomaterial to conform at least partially to the shape of the surface feature and adhere to the surface feature either directly or via an intermediate layer therebetween without causing fracture in nanomaterial.
