Reversible spin switching in molecular arrays.
(a) The dI/dV mapping (upper panel) and simultaneously acquired topography (lower panel) of a H-MnPc molecular array (Kondo OFF state). (b) The dI/dV mapping (upper panel) and simultaneously acquired topography (lower panel) of the same molecular array as a but with a few selected molecules converted to the MnPc state (Kondo ON). For both (a) and (b), the dI/dV mappings were taken at 6 mV. Note that the MnPc state (Kondo ON) can be erased and converted back to H-MnPc state (Kondo OFF) by adsorption of additional hydrogen. (c) The dI/dV mapping (upper panel) and topography (lower panel) of a close-packed molecular array with pre-designed Kondo pattern by switching selected molecules from the H-MnPc to the MnPc states within the array. The dI/dV mapping was taken at 6 mV. (d) The Fano factor q and Kondo temperature TK of Kondo ON states after multiple-cycles of spin switching, indicating the robustness of the spin manipulation process.
