International Classification:

B32B 1102

US Classification:

428 341, 4283155, 4283157, 4283191, 428694 B, 428694 BA, 428694 TC, 428694 TP, 427131, 536 231

Abstract:

A laminar structure upon a substrate is formed from a) a lattice layer comprising DNA (deoxyribonucleic acid) segments arranged to form cells of the lattice layer, and b), at least one nanoparticle being disposed within each cell of the lattice layer. The nanoparticles are preferably of substantially uniform diameter not exceeding 50 nanometers. A coating may be applied to adhere the the particles to the substrate and to maintain their substantially uniform spaced-apart relationship. The DNA lattice layer is fabricated using known automated synthetis methods, and is designed to contain specific nucleotide base sequences which cause the DNA to form an ordered array of openings, or lattice cells, by self-assembly. Self-assembly of the DNA lattice may be at an air-liquid interface, or in solution. A preferred embodiment is a magnetic storage medium in which the particles are magnetic particles with diameters in the range of 5-20 nm.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H01L 2131

US Classification:

438778, 438780, 438782, 438788, 438792

Abstract:

This invention describes a new method for forming and depositing thin films of crystalline dielectric materials. The present technique uses chemical synthesis to control the granularity and thickness of the dielectric films. This method has several key advantages over existing technologies, and facilitates the integration of crystalline dielectric materials into high-density memory devices.

International Classification:

G01R033/02
G11B005/66

US Classification:

324252, 428323, 428336

Abstract:

A magnetic-field sensor device comprises at least two electrodes; an insulating layer separating the at least two electrodes; at least one layer of chemically-synthesized magnetic nanoparticles disposed at or above a level with the insulating layer, and disposed between the at least two electrodes; and an organic spacer surrounding each of the chemically-synthesized magnetic nanoparticles. A deviation between diameters of different ones of the nanoparticles is less than 15%. Moreover, the chemically-synthesized magnetic nanoparticles range in size between 2 nm and 20 nm in diameter.

International Classification:

G01B 7/34

US Classification:

250306, 435 6, 427256, 428327, 73105, 977924

Abstract:

A structure and method for improving the spatial resolution of a scanning probe microscope (SPM) tip, which has been coated with a layer of chemically-synthesized nanoparticles. The nanoparticles are either single-species or heterogeneous, such that the single-species nanoparticles can be either ferromagnetic, paramagnetic, superparamagnetic, antiferromagnetic, ferrimagnetic, magneto-optic, ferroelectric, piezoelectric, superconducting, semiconducting, magnetically-doped semiconducting, insulating, fluorescent, or chemically catalytic. The layer of nanoparticles is at least two nanoparticles thick, or alternatively, is a single layer of nanoparticles thick, or alternatively, is a single layer of nanoparticles thick and covers only the tip apex portion of the tip, or alternatively, only a single nanoparticle is affixed to the tip apex. Alternatively, the layer of nanoparticles is transformed into an electrically-continuous magnetic film by annealing at a high temperature.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

D01F 9/127

US Classification:

4234473, 423445 B

Abstract:

The invention is directed to a method of positioning nanoparticles on a patterned substrate. The method comprises providing a patterned substrate with selectively positioned recesses, and applying a solution or suspension of nanoparticles to the patterned substrate to form a wetted substrate. A wiper member is dragged across the surface of the wetted substrate to remove a portion of the applied nanoparticles from the wetted substrate, and leaving a substantial number of the remaining portion of the applied nanoparticles disposed in the selectively positioned recesses of the substrate. The invention is also directed to a method of making carbon nanotubes from the positioned nanoparticles.
