Electronic memory effects in self-assembled monolayer systems

Theoretical and experimental investigation into environment dependence and electric properties for volatile memory based on methyl-red dye thin film

“…Moreover, if compared with similar volatile organic memories, this device does not show a good retention time because was performed by organic self-assembled monolayers fabricated with donor and acceptor electrons molecular groups. Despite that, the peak current for this devices is less than 2.5 nA, very small compared with our memory device [22].…”

Single molecular switch based on thiol tethered iron(II)clathrochelate on gold

“…Two types of molecular switching behaviour have been observed thus far-switching due to an applied external voltage between the electrodes and stochastic switching attributed to statistical fluctuations in the film or molecule [2,[8][9][10]. Switching between two conductance states has been observed for different molecular systems in experiments conducted on ensembles of molecules in a sealed nano-pore system [2,11,12]. These molecular ensembles can be used for moleculebased memory devices, as the conductance state is set by a voltage pulse [11][12][13].…”

Charge transmission through a molecular wire: The role of terminal sites for the current-voltage behavior

“…They could be demonstrated to operate as molecular switches, 1,2 diodes, [3][4][5]7 transistors, 6-9 sensors, 10 memory storage devices, 11,12 etc. The current through a single molecule is controlled by a whole set of different factors: the electronic structure of the molecule, the type of molecule-electrode coupling, and the position of the lowest unoccupied/highest occupied molecular orbitals ͑LUMO/ HOMOs͒ with respect to the Fermi levels of each electrode, to name a few.…”
