Abstract:
A composite material includes a carbon nanotube, and plural pentacene molecules bonded to the carbon nanotube. A method of forming the composite layer, includes depositing on a substrate a dispersion of soluble pentacene precursor and carbon nanotubes, heating the dispersion to remove solvent from the dispersion, heating the substrate to convert the pentacene precursor to pentacene and form the carbon nanotube-pentacene composite layer.

Abstract:
A method for resetting a spin-transfer based random access memory system, the method comprising, inducing a first current through a first conductor, wherein the first current is operative to propagate a magnetic domain wall in a ferromagnetic film layer and the propagation of the magnetic domain wall is further operative to change the direction of a magnetic state of a first free layer magnet, and inducing a second current only through a second conductor, wherein the second current is operative to further propagate the magnetic domain wall in the ferromagnetic film layer and the propagation of the magnetic domain wall is further operative to change the direction of a magnetic state of a second free layer magnet.
Abstract:
A method (and structure) for controlling a beam used to generate a pattern on a target surface includes generating a beam of charged particles and directing the beam to a mask surface and causing the beam to be either absorbed by or reflected from the mask surface, thereby either precluding or allowing the beam to strike the target surface, based on a reflection characteristic of the mask surface.
Abstract:
An aberration-correcting microscopy instrument is provided. The instrument has a first magnetic deflector disposed for reception of a first non-dispersed electron diffraction pattern. The first magnetic deflector is also configured for projection of a first energy dispersed electron diffraction pattern in an exit plane of the first magnetic deflector. The instrument also has an electrostatic lens disposed in the exit plane of a first magnetic deflector, as well as a second magnetic deflector substantially identical to the first magnetic deflector. The second magnetic deflector is disposed for reception of the first energy dispersed electron diffraction pattern from the electrostatic lens. The second magnetic deflector is also configured for projection of a second non-dispersed electron diffraction pattern in a first exit plane of the second magnetic deflector. The instrument also has an electron mirror configured for correction of one or more aberrations in the second non-dispersed electron diffraction pattern. The electron mirror is disposed for reflection of the second non-dispersed electron diffraction pattern to the second magnetic deflector for projection of a second energy dispersed electron diffraction pattern in a second exit plane of the second magnetic deflector.
Abstract:
The present invention broadly concerns layered structures of substantially-crystalline materials and processes for making such structures. More particularly, the invention concerns epitaxial growth of a substantially-crystalline layer of a first material on a substantially-crystalline second material different from the first material utilizing an approximately one monolayer thick monovalent surfactant element.

Abstract:
An energy filtering microscopy instrument is provided. An objective lens is disposed for reception of electrons in order to form an electron diffraction pattern in a backfocal plane of the objective lens. An entrance aperture disposed in the backfocal plane of the objective lens for filtering a slice of the electron diffraction pattern. A magnetic deflector has an entrance plane and an exit plane. The entrance aperture is disposed in the entrance plane. The magnetic deflector is disposed to receive the slice of the electron diffraction pattern and project an energy dispersed electron diffraction pattern to the exit plane. An exit aperture is disposed in the exit plane of the magnetic deflector for selection of desired electron energy of the energy dispersed electron diffraction pattern.
Abstract:
Fabrication of atomic step-free regions on a substrate surface is achieved by first forming a two-dimensional pattern on the substrate. The pattern is preferably a grating comprising an array of troughs or mesas which are separated from one another by a plurality of ridges or trenches. Any atomic steps on the flat top surfaces of the troughs or mesas are moved into barrier regions formed by the ridge or trench sidewalls during a high temperature annealing or deposition step, thereby leaving the flat surfaces of the troughs and mesas free of atomic steps. Structures having step-free regions large enough to accommodate micron sized devices having nanometer sized features are thereby formed.
