Query: p-band engineering in artificial electronic lattices   Artificial electronic lattices, created atom by atom in a scanning tunneling
microscope, have emerged as a highly tunable platform to realize and
characterize the lowest-energy bands of novel lattice geometries. Here, we show
that artificial electronic lattices can be tailored to exhibit higher-energy
bands. We study p-like bands in four-fold and three-fold rotationally symmetric
lattices. In addition, we show how an anisotropic design can be used to lift
the degeneracy between p_x- and p_y-like bands. The experimental measurements
are corroborated by muffin-tin and tight-binding calculations. The approach to
engineer higher-energy electronic bands in artificial quantum systems
introduced here enables the realization of complex band structures from the
bottom up.
