(a) CoPc molecules adsorbed on NaCl-partially-covered Cu(100) (100 nm×160 nm, V_b = 3.5 V, I_t = 65 pA). (b) The molecules on Cu(100) (11 nm×11 nm, V_b = 1.5 V, I_t = 80 pA) and (c) NaCl layers (11 nm×11 nm, V_b = 2.5 V, I_t = 35 pA). The insets in panels (b) and (c) are the atomically resolved images of Cu(100) and NaCl/Cu(100), respectively.
