    摘要: An electric field activated molecular system, preferably bi-stable, configured within an electric field generated by a pair of electrodes is provided for use, e.g., as electronic ink or other visual displays. The molecular system has an electric field induced band gap change that occurs via a change (reversible or irreversible) of the extent of the electron conjugation via chemical bonding change to change the band gap, wherein in a first state, there is substantial conjugation throughout the molecular system, resulting in a relatively smaller band gap, and wherein in a second state, the substantial conjugation is destroyed, resulting in a relatively larger band gap. The changing of substantial conjugation may be accomplished in one of the following ways: (1) charge separation or recombination accompanied by increasing or decreasing electron localization in the molecule; or (2) change of substantial conjugation via charge separation or recombination and&pgr;-bond breaking or making. A primary advantage of the molecular system is improved contrast. Because the colorant of the present invention is molecular and thus effectively monoplanar, there should be no backside reflection or excessive scattering from the colorant. A second advantage of the present invention is improved resolution. Finally, each molecule of the present invention will latch to stabilize one or the other of its color states.

    摘要: A method is provided for printing electronic and opto-electronic circuits. The method comprises: (a) providing a substrate; (b) providing a film-forming precursor species; (c) forming a substantially uniform and continuous film of the film-forming precursor species on at least one side of the substrate, the film having a first electrical conductivity; and (d) altering portions of the film with at least one conductivity-altering species to form regions having a second electrical conductivity that is different than the first electrical conductivity, the regions thereby providing circuit elements. The method employs very simple and continuous processes, which make the time to produce a batch of circuits very short and leads to very inexpensive products, such as electronic memories (write once or rewriteable), electronically addressable displays, and generally any circuit for which organic electronics or opto-electronics are acceptable.

    摘要: 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.

    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 gated nanoscale switch operates as a resonant tunneling device. A conductive channel is formed of a pair of conductive molecular wires and a conductive nanoparticle. Each molecular wire is bound, at one end, to the conductive nanoparticle and, at the opposed end, to one of a pair of electrodes. The structure is located upon a dielectric layer that overlies a conductive substrate. The device may be arranged to operate as a switch with the conductive substrate acting as a gate electrode. Alternatively, the device may be employed to measure the electrical (current versus voltage) characteristics of the molecular wires.

    摘要: A method for forming first and second linear structures of a first composition that meet at right angles, there being a gap at the point at which the structures meet. The linear structures are constructed on an etchable crystalline layer having the first composition. First and second self-aligned nanowires of a second composition are grown on this layer and used as masks for etching the layer. The self-aligned nanowires are constructed from a material that has an asymmetric lattice mismatch with respect to the crystalline layer. The gap is sufficiently small to allow one of the structures to act as the gate of a transistor and the other to form the source and drain of the transistor. The gap can be filled with electrically switchable materials thereby converting the transistor to a memory cell.
