Metal nanostructures and thin binary alloys on 2D materials

Two-dimensional materials provide several advantages for the growth of metal nanostructures over traditional substrates.

PI: Jani Kotakoski

Replacing strict condition for lattice matching between the substrate and the grown material with van der Waals epitaxy or completely relaxing this requirement allows the growth of low-strain or strain-free nanostructures. For example, the growth of novel 2D binary alloy CuAu and titanium islands have already been demonstrated on graphene. Eventually, these structures may find use in plasmonic or catalysis applications.
