“…The formation of dimers or oligomers via disulfide bond formation during the redox cycles might also affect the switching. Interestingly, it is in principle possible to artificially enhance the on-off ratio of a switchable molecular device further, provided the device is brought in the regime of multiple inelastic co-tunneling, e.g., by using smaller nanoparticles [58]. Overall, these experiments demonstrate that nanoparticle arrays can be used as a "nanoscale breadboard" to assemble molecular junction networks showing active functionality at the network level.…”

Arrays of metal nanoparticles in an organic matrix have attracted a lot of interest due to their diverse electronic and optoelectronic properties. By varying parameters such as the nanoparticle material, the matrix material, the nanoparticle size, and the interparticle distance, the electronic behavior of the nanoparticle array can be substantially tuned and controlled. For strong tunnel coupling between adjacent nanoparticles, the assembly exhibits conductance properties similar to the bulk properties of the nanoparticle material. When the coupling between the nanoparticles is reduced, a metal insulator transition is observed in the overall assembly. Recent work demonstrates that nanoparticle arrays can be further utilized to incorporate single molecules, such that the nanoparticles act as electronic contacts to the molecules. Furthermore, via the excitation of the surface plasmon polaritons, the nanoparticles can be optically excited and electronically read out.

“…A power law in IV curve is predicted by the co-tunneling theory for weakly coupled NPs, and the exponent η = 2 j − 1, where j is the number of junctions involved in the co-tunneling process. [30] However, such a picture needs correction before applied to AIs, since the localization length for co-tunneling may be very large, lin>>a.…”

Abstract:The Anderson insulating states in Au nanoparticle assembly are identified and studied under the application of magnetic fields and gate voltages. When the inter-nanoparticle tunneling resistance is smaller than the quantum resistance, the system showing zero Mott gap can be insulating at very low temperature. In contrast to Mott insulators, Anderson insulators exhibit great negative magnetoresistance, inferring charge de-localization in a strong magnetic field. When probed by the electrodes spaced by ~200 nm, they also exhibit interesting gate-modulated current similar to the multi-dot single electron transistors. These results reveal the formation of charge puddles due to interplay of disorder and quantum interference at low temperatures.

“…This and other granular systems have been in use from the early days of measuring single-charge transport [31], but are still the topic of active research in the context of molecular electronics [32,33]. For clarity of presentation, we restrict our discussion to the case of a linear chain of capacitively coupled small islands.…”

“…The position of the surface charges, however, can still be detected by an algorithm similar to the previous section. To demonstrate the feasibility of charge mapping in more than one dimension, we consider a a planar metal nanoparticle network [31,33]. This system and its variants are broadly used for studying the electronic transport in nanostructured devices.…”

Single molecules that exhibit narrow optical transitions at cryogenic temperatures can be used as local electricfield sensors. We derive the single-charge sensitivity of aromatic organic dye molecules, based on quantum mechanical considerations. Through numerical modeling, we demonstrate that by using currently available technologies it is possible to optically detect charging events in a granular network with a sensitivity better than 10−5 e/ √ Hz and track positions of multiple electrons, simultaneously, with nanometer spatial resolution. Our results pave the way for minimally invasive optical inspection of electronic and spintronic nanodevices and building hybrid optoelectronic interfaces that function at both single-photon and single-electron levels.
