  • Publication number: 20090121210
    Abstract: This invention provides a new method of forming a self-assembling monolayer (SAM) of alcohol-terminated or thiol-terminated organic molecules (e.g. ferrocenes, porphyrins, etc.) on a silicon or other group IV element surface. The assembly is based on the formation of an E-O— or an E-S— bond where E is the group IV element (e.g. Si, Ge, etc.). The procedure has been successfully used on both P- and n-type group IV element surfaces. The assemblies are stable under ambient conditions and can be exposed to repeated electrochemical cycling.

  • Publication number: 20090056994
    Abstract: Embodiments of the present invention provide methods of treating a surface of a substrate. In one particular aspect, embodiments of the present invention provide methods of treating a surface of a substrate that promote binding of one or more metal elements to the surface. According to some embodiments of the invention, films are formed on any conducting, semiconductive or non-conductive surface, by thermal reaction of molecules containing reactive groups in an organic solvent or in aqueous solution. The thermal reaction may be produced under a variety of conditions. In another aspect, the present invention provides a printed circuit board, comprising: at least one substrate; a layer of organic molecules attached to the at least one substrate; and a metal layer atop said layer of organic molecules.

  • Patent number: 7452572
    Abstract: This invention provides novel methods for the formation of redox-active polymers attached to surfaces. In certain embodiments, the methods involve providing redox-active molecules bearing at least a first reactive site or group and a second reactive site or group; and contacting the surface with the redox-active molecules where the contacting is under conditions that result in attachment of said redox-active molecules to said surface via the first reactive site or group and attachment of redox-active molecules via the second reactive site or group, to the redox-active molecules attached to the surface thereby forming a polymer attached to said surface where the polymers comprise at least two of said redox-active molecules.

  • Publication number: 20070212897
    Abstract: This invention provides a new procedure for attaching molecules to semiconductor surfaces, in particular silicon. The molecules, which include, but are not limited to porphyrins and ferrocenes, have been previously shown to be attractive candidates for molecular-based information storage. The new attachment procedure is simple, can be completed in short times, requires minimal amounts of material, is compatible with diverse molecular functional groups, and in some instances affords unprecedented attachment motifs. These features greatly enhance the integration of the molecular materials into the processing steps that are needed to create hybrid molecular/semiconductor information storage devices.

  • Patent number: 7074519
    Abstract: This invention provides a new design and fabrication for a three-dimensional crossbar architecture embedding a sub-micron or nanometer sized hole (called a molehole) in each cross-region. Each molehole is an electrochemical cell consisting of two or more sectional surfaces separated by a non-conductor (e.g. a dialectric layer and solid electrolyte). When used in electrochemical molecular memory device (EMMD), the architecture provides unique features such as a nano-scale electroactive surface, no interaction between memory elements, and easier miniaturization and integration.
