  • Publication number: 20220383924
    Abstract: A two-bit memory device having a layer structure containing in order a bottom layer, a molecular layer containing a chiral compound having at least one polar functional group, and a top layer, which is electrically conductive and ferromagnetic. The chiral compound acts as a spin filter for electrons passing through the molecular layer. The chiral compound is of flexible conformation and has a conformation-flexible molecular dipole moment. An electrical resistance of the layer structure for an electrical current running from the bottom layer to the top layer has at least four distinct states which depend on the magnetization of the top layer and on the orientation of the conformation-flexible dipole moment of the chiral compound. Furthermore, a method for operating the two-bit memory device and an electronic component containing at least one two-bit memory device.

  • Publication number: 20060154489
    Abstract: The invention concerns a structured semiconductor surface as basis for molecular electronics or molecular electronics-based bio-sensors. The starting point is a heterostructure consisting of two undoped layers of a semiconductor material that are separated by an extremely thin (a few nm) layer of a different semiconductor material. This material stack is cleaved perpendicular to the layer planes and the middle layer is selectively etched. Source- and drain contacts for conductive organic “wires” are by built by evaporation with a thin metal film. The middle conductive layer can be employed as electrostatic gate. An assembly for contacting a few up to single wires can be obtained by two sequential separations and evaporations. Possible organic wires are e.g. molecules with conjugated (E-electron system, DNA-oligonucleotides or carbon nanotubes.

  • Publication number: 20050266568
    Abstract: A molecule-releasing apparatus includes a releasing unit configured to release molecules, wherein the releasing unit comprises at least one conductive member and releases molecules electrically interacting with the conductive member to which a potential is applied, from the conductive member by changing the potential so as to remove the interaction. In a moleculue-releasing method, molecules electrically attracted to two or more conductive members are released by electrical repulsion from the conductive members at different times. The molecule-releasing apparatus and molecule-releasing method are capable of efficiently releasing or transferring various useful molecules such as DNA molecules, into targets such as cells and can be safely applied for use in gene therapy and other applications.

  • Publication number: 20050069932
    Abstract: In an analyte evaluating device comprising a carrier body that can be bound with an analyte having a fluorescence-labeled part that can emit fluorescence by light received when the distance between the fluorescence-labeled part and the carrier body is enlarged, at least one factor selected from the group consisting of a light irradiation angle, a light irradiation intensity, a light irradiation area, a fluorescence detection angle, a fluorescence detection area, the shape of the carrier body, the surface area of the carrier body, a salt concentration in a medium for use in the detection, and the adhesion density of analytes on the carrier body, is made to be adjustable. A high sensitivity is realized. Evaluation is possible without introducing fluorescence-labeled parts. Evaluation for a tiny amount of sample is possible. It is also possible to evaluate objects in a mixed state. Miniaturized, complex, and integrated devices are possible.
