    摘要: A route to the fabrication of electronic devices is provided, in which the devices consist of two crossed wires sandwiching an electrically addressable molecular species. The approach is extremely simple and inexpensive to implement, and scales from wire dimensions of several micrometers down to nanometer-scale dimensions. The electronic devices can be used to produce crossbar switch arrays, logic devices, memory devices, and communication and signal routing devices. The construction of molecular electronic devices is achieved on a length scale than can range from micrometers to nanometers via a straightforward and inexpensive chemical assembly procedure. The molecular switchable devices in the cross-bar geometry are configurable while the conformational change is controlled by intramolecular forces that are stronger than hydrogen bonding. The method of the present invention is directed to configuring an ensemble of molecular switches in a prescribed manner in cross-bar geometry and then making such configuration either substantially permanent or stable with respect to temperature fluctuations.

    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 null-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 laser beam frequency modulation demodulator is disclosed utilizing the highly linear frequency versus voltage characteristic of the absorption resonance provided by a Stark-effect cell. An error signal, generated by dither modulation of the Stark-effect cell voltage, is fed back to the Stark-effect cell via a low-pass filter to cause the absorption resonance to track the instantaneous frequency of the laser beam. The feedback signal applied to the Stark-effect cell has an amplitude proportional to the frequency modulation on the laser beam.

    摘要: Electromagnetic transient coherent effects such as photon echo and optical nutation are produced by directing cw laser radiation into a gaseous medium such as C13H3F and NH2D, contained in a Stark cell, and by applying Stark pulses which shift the molecular levels into resonance with the cw laser radiation. The effects lend themselves to applications in optical modulation, data communication, superradiance, spectroscopy, memory and pulse height to frequency conversion, among others.

    摘要: In a beam-addressed optical memory, the size of the focused light spot is electrically controlled to provide successively larger spot sizes for reading, writing and erasing. A body of material having electric field controllable optical properties which are capable of altering the intensity distribution or the wave front shape of the light beam is positioned between the light source and the focusing means. Electrodes controllably apply a non-uniform electric field to the body such that a nonuniform change in the intensity distribution or the wave front shape of the light beam occurs, thereby causing a change in the size of the focused light spot.

    摘要: A display device having a layer of semiconductive material with an optical absorption band whose edge shifts in the presence of a strong electric field. The layer of semiconductive material is subjected to an electric field that uniformly decreases in strength in one direction along the layer of semiconductive material. The strength of the electric field is changed to control transmission of light by the layer of semiconductive material to provide a lighted display. The light has a wavelength related to the edge of the optical absorption band of the semiconductive material.
