Designing an artificial Lieb lattice on a metal surface
Designing an artificial Lieb lattice on a metal surface
Recently, several experiments [K. K. Gomes et al., Nature (London) 483, 306 (2012); S. Wang et al., Phys. Rev. Lett. 113, 196803 (2014)] have illustrated that metal surface electrons can be manipulated to form a two-dimensional (2D) lattice by depositing a designer molecule lattice on a metal surface.
