The transition behavior of FePc on Ag(1 1 0)

The transition behavior of FePc on Ag(1 1 0) has been investigated by room temperature scanning tunneling microscopy (STM) and density functional theory (DFT) simulation. After FePc molecules deposited on Ag(1 1 0) surface, two adsorption structures were observed. The pathway between these different configurations was investigated by DFT simulation. The transition of electronic structures of FePc/Ag(1 1 0) interface and change in work function during the transformation were investigated by the calculated density of states (DOS) together with the application of induced density of interface states (IDIS).
