Inducing dynamic strain in gold nanoparticle-supported graphene by focused laser irradiation

What is it about?

We have shown a method for the preparation of hemispherical gold nanoparticles by local annealing of gold thin films using focused laser beam. The method resulted in a patterned surface, with closely spaced nanoparticles formed at arbitrarily chosen microscale areas. Graphene grown by chemical vapour deposition was transferred onto the prepared nanoparticles. We have shown that laser irradiation induced strain in the nanoparticle-supported graphene, which turned out to be completely reversible.
