Low bias negative differential resistance with dual-peaks based on octacene molecular device

Publication date: Available online 3 July 2019Source: Physics Letters AAuthor(s): J. Zhang, Z. Qin, B. Xu, G. SongAbstractBased on non-equilibrium Green's function and density functional theory, a first-principles study of the transport properties of a molecular device is performed. This device is composed of two octacene molecules separated by a ethyl barrier, which are then linked to Ag leads through thiolates. The device shows low bias negative differential resistance effect with dual-peaks, which may be useful for designing molecular devices with low power-dissipation and multi-function in the future.
