A molecular layer includes a Langmuir-Blodgett (LB) film of a molecule connected to a plurality of active device molecules, the molecule having a moiety with first and second connecting groups at opposed ends of the moiety. Each of the plurality of active device molecules includes a switching moiety, a self-assembling connecting group at one end of the switching moiety, and a linking group at an opposed end of the moiety. One or more defect site(s) exist between the plurality of active device molecules. A respective number of the first connecting groups of the LB film are connected to the plurality of active device molecules via at least some of the linking groups such that the LB film covers the plurality of active device molecules and the one or more defect site(s).

Langmuir-Blodgett films are provided in which a molecule is chemically bonded with a bottom electrode substrate as part of a crossed wire device comprising two electrodes and a molecular layer therebetween. The molecule, which comprises a switchable moiety and a connecting moiety, is provided with a photolabile capping group attached to the connecting moiety. The photolabile capping group temporarily caps the reactive connecting group of the molecule. The capped molecules are processed to form a LB film on the water-air interface of water. The films are then exposed to UV light. The photolabile capping group decomposes to give back the connecting group, which remains in the water. As the uncapped LB films are transferred to a bottom electrode substrate, the surface of the electrode reacts with the reactive connecting group of the molecule to form a chemically bonded LB layer on the substrate, thereby providing improved LB films.

Various nanoscale logic gates are disclosed. An alternating current (“AC”) source is superimposed on a direct-current (“DC”), largely resistor-based nanoscale logic circuit in order to provide distinguishable, AC current or voltage logical output signals despite potentially narrow DC-voltage or DC-current ranges produced by the resistor-based nanoscale logic circuit. AC-enhanced AND, OR, NAND, and NOR nanoscale logic gates are provided as four specific embodiments of the present invention.
摘要:
An optical sensor is provided, comprising (a) a silicon nanowire of finite length having an electrical contact pad at each end thereof; and (b) a plurality of self-assembled molecules on a surface of the silicon nanowire, the molecules serving to modulate electrical conductivity of the silicon nanowire by either a reversible change in dipole moment of the molecules or by a reversible molecule-assisted electron/energy transfer from the molecules onto the silicon nanowire. Further, a method of making the optical sensor is provided. The concept of molecular self-assembly is applied in attaching functional molecules onto silicon nanowire surfaces, and the requirement of molecule modification (hydroxy group in molecules) is minimal from the point view of synthetic difficulty and compatibility. Self-assembly will produce well-ordered ultra-thin films with strong chemical bonding on a surface that cannot be easily achieved by other conventional methods.
摘要:
A method and mold for creating nanoscale patterns in an ion-selective polymer membrane is provided, in which a mold comprising a substrate and a molding layer having at least one protruding feature is imprinted on the ion-selective polymer membrane, thereby creating a recessed feature in the membrane. Protruding features having nanoscale dimensions can be created, e.g., by using self-assembled nanostructures as a shadow mask for etching a molding layer. In one embodiment, an imprinted ion selective polymer membrane, suitable for use as a solid electrolyte, is adapted for use in an electrochemical device or fuel cell by adding a metal catalyst to one portion of the membrane to serve as a catalytic electrode.
摘要:
A molecular memory system that includes a protective layer that is disposed over a molecular recording layer is described. The protective layer enables a scanning probe to write information to and read information from a molecular memory element by direct electrical contact without substantial risk of damage to either the scanning probe or the molecular recording medium. In this way, the invention avoids the high emission currents, which may damage the probe electrode or the recording media, or both, and avoids other difficulties often associated molecular memory systems with non-contacting probe electrodes.
