摘要： A method is provided for fabricating molecular electronic devices comprising at least a bottom electrode and a molecular switch film on the bottom electrode. The method includes forming the bottom electrode by a process including: cleaning portions of the substrate where the bottom electrode is to be deposited; pre-sputtering the portions; depositing a conductive layer on at least the portions; and cleaning the top surface of the conductive layer. Advantageously, the conductive electrode properties include: low or controlled oxide formation (or possibly passivated), high melting point, high bulk modulus, and low diffusion. Smooth deposited film surfaces are compatible with Langmuir-Blodgett molecular film deposition. Tailored surfaces are further useful for SAM deposition. The metallic nature gives high conductivity connection to molecules. Barrier layers may be added to the device stack, i.e., Al2O3 over the conductive layer.

摘要： A switching device includes at least one bottom electrode and at least one top electrode. The top electrode crosses the bottom electrode at a non-zero angle, thereby forming a junction. A metal oxide layer is established on at least one of the bottom electrode or the top electrode. A molecular layer including a monolayer of organic molecules and a source of water molecules is established in the junction. Upon introduction of a forward bias, the molecular layer facilitates a redox reaction between the electrodes, thereby reducing a tunneling gap between the electrodes.

摘要： A molecule for Langmuir-Blodgett (LB) deposition of a molecular layer. The molecule includes at least one switching moiety, a hydrophilicity-modifiable connecting group attached to one end of the moiety, and a hydrophilicity-non-modifiable connecting group attached to the other end of the moiety. The hydrophilicity-modifiable connecting group is transformable to a temporary end group upon adjustment in pH of the aqueous environment containing the molecule. The temporary end group is more hydrophilic than the hydrophilicity-modifiable connecting group and the hydrophilicity-non-modifiable connecting group. The difference in hydrophilicity between the temporary end group and the hydrophilicity-non-modifiable connecting group causes formation of a substantially well-oriented, uniform LB film at a water/solvent and/or water/air interface.

摘要： Various aspects of the present invention are directed to electric-field-enhancement structures and detection apparatuses that employ such electric-field-enhancement structures. In one aspect of the present invention, an electric-field-enhancement structure includes a substrate having a surface. The substrate is capable of supporting a planar mode having a planar-mode frequency. A plurality of nanofeatures is associated with the surface, and each of nanofeatures exhibits a localized-surface-plasmon mode having a localized-surface-plasmon frequency approximately equal to the planar-mode frequency.
