current-voltage characteristic rectification behaviour is observed due

to the asymmetry in this molecule and junctions. In addition, negative

differential resistance is observed which indicates contribution of

holes in the conductance through this molecule....

this study are semi-infinite FM electrodes with finite cross-section. Obvious rectification effect is

observed in the C59N molecule which is connected to the FMelectrodes asymmetrically. This effect

is more in the P alignment of FM electrodes...
