Abstract EN
The strain effect on graphene-encapsulated Au nanoparticles is investigated.
A finite-element calculation is performed to simulate the strain distribution and morphology of the monolayer and multilayer graphene-encapsulated Au nanoparticles, respectively.
It can be found that the inhomogeneous strain and deformation are enhanced with the increasing shrinkage of the graphene shell.
Moreover, the strain distribution and deformation are very sensitive to the layer number of the graphene shell.
Especially, the inhomogeneous strain at the interface between the graphene shell and encapsulated Au nanoparticles is strongly tuned by the graphene thickness.
For the mono- and bilayer graphene-encapsulated Au nanoparticles, the dramatic shape transformation can be observed.
However, with increasing the graphene thickness further, there is hardly deformation for the encapsulated Au nanoparticles.
These simulated results indicate that the strain and deformation can be designed by the graphene layer thickness, which provides an opportunity to engineer the structure and morphology of the graphene-encapsulated nanoparticles.
