Voltage-dependent conductance states of a single-molecule junction
Ag–Sn-phthalocyanine–Ag junctions are shown to exhibit three conductance states. While the junctions are conductive at low bias, their impedance drastically increases above a critical bias. Two-level fluctuations occur at intermediate bias. These characteristics may be used to protect a nanoscale circuit.
Further experiments along with calculations reveal that the self-limiting conductance of the junctions is due to reversible changes of the junction geometry.
