“…Not only can the local atomic or molecular configurations be probed before and after flipping the switch, but the operation process itself can be followed by recording for example current traces as a function of time 26 and even be modified 27 . Supplementary Information, Fig.…”

The development of a variety of nanoscale applications 1, 2 requires the fabrication and control of atomic [3][4][5] or molecular switches 6, 7 that can be reversibly operated by light 8 , a short range force 9, 10 , electric current 11,12 or some other external stimulus [13][14][15] . In order for such molecules to be used as electronic components, they should be directly Fig. 1d and f) at ambient temperatures, the process being called tautomerization 24,

We report the study of both occupied and unoccupied electronic states of biphenyl adsorbed on Si͑100͒ by using synchrotron radiation ultraviolet photoemission spectroscopy, x-ray photoemission spectroscopy, and near-edge x-ray absorption fine structure spectroscopy. The results are compared with calculations of the occupied densities of states. Evidence is given of two main effects: ͑i͒ a down shift in energy of the second highest occupied molecular orbital of the strongly chemisorbed configuration at room temperature compared to the weakly chemisorbed configuration at low temperatures and ͑ii͒ an energy splitting of some of the occupied and unoccupied states due to the different interactions of the two phenyl rings of the molecule. The electronic structure of biphenyl on Si͑100͒ appears to be an appropriate test for state of the art experimental and theoretical methods.

“…Recent scanning-tunneling microscopy (STM) experiments [5,6,7,8,9] have shown bistability and multistability of neutral and charged states. Random and controlled switching of single molecules [10,11,12], as well as conformational memory effects [6,9,13,14] have been recently investigated. Other groups have observed memory effects in graphene [15,16,17] and carbon nanotubes [18,19,20].…”

Vibration induced memory effects and switching in ac-driven molecular nanojunctions

Abstract. We investigate bistability and memory effects in a molecular junction weakly coupled to metallic leads with the latter being subject to an adiabatic periodic change of the bias voltage. The system is described by a simple Anderson-Holstein model and its dynamics is calculated via a master equation approach. The controlled electrical switching between the many-body states of the system is achieved due to polaron shift and Franck-Condon blockade in the presence of strong electron-vibron interaction. Particular emphasis is given to the role played by the excited vibronic states in the bistability and hysteretic switching dynamics as a function of the voltage sweeping rates. In general, both the occupation probabilities of the vibronic states and the associated vibron energy show hysteretic behaviour for driving frequencies in a range set by the minimum and maximum lifetimes of the system. The consequences on the transport properties for various driving frequencies and in the limit of DC-bias are also investigated.
