Charge density wave. Real space electronic density nCB of the substrate conduction band for the strongly coupled regime and nf ~ 0.7 for a L = 3, b L = 7 and c L = 9. Black (white) colours indicate large (small) electronic density. For L = 3, we observe localized states around the adatom (the adatom, not shown, is located at the centre of the black circles). As L increases, we observe a delocalization, which is concomitant with Kondo physics (see Discussion hereafter). For the limit of diluted solids, corresponding to L = 9 and larger, we observe the formation of a charge density wave (CDW), where localized states develop in between adatoms. The CDW is concomitant with the formation of a pseudogap (see Discussion hereafter)
