Electronic properties of Li and K on graphene: top, hollow and bridge configurations

In this work, I present an analytical Tight Binding Model (TBM), for graphene with adsorbate atoms of lithium and potassium, in different positions of adsorption. The configurations analyzed here are: a) Top site (adsorbate atom on top of the carbon atom of the sublattice A of graphene), b) Hollow s...
