摘要:
Apparatus using amorphous magnetic compositions having uniaxial anisotropy include bubble domain apparatus, light modulating apparatus, permanent magnet systems, and tape and disc information handling systems. The amorphous magnetic composition can be prepared in thin film or bulk form or as particles in a binder. The anisotropy can be parallel to the plane of a film of this material or perpendicular to the film plane. The amorphous material is comprised of a single element or is a multicomponent system where as at least one of the components has an unimpaired spin so that the composition has a net magnetic moment. The amorphous composition exists as a microcrystalline structure having localized atomic ordering over a distance 25-100 A, or as a substantially amorphous structure where localized atomic ordering is over distances less than 25A. Binary and ternary compositions, either alloys or compounds, are suitable. The magnetic properties of the compositions can be changed during fabrication or after fabrication, and the compositions can be doped readily without adversely affecting magnetic properties.

Inexpensive semiconductors are produced by depositing a single crystal or large grained silicon on an inexpensive substrate. These semiconductors are produced at low enough temperatures such as temperatures below the melting point of glass. Semiconductors produced are suitable for semiconductor devices such as photovoltaics or displays
摘要:
A method is disclosed for making semiconductor films from a eutectic alloy comprising a metal and a semiconductor. Through heterogeneous nucleation said film is deposited at a deposition temperature on relatively inexpensive buffered substrates, such as glass. Specifically said film is vapor deposited at a fixed temperature in said deposition temperature where said deposition temperature is above a eutectic temperature of said eutectic alloy and below a temperature at which the substrate softens. Such films could have widespread application in photovoltaic and display technologies.

A molecular manipulator includes a light-sensitive molecule, including a double bond, which changes a cis-trans configuration of the double bond in response to illumination by light of a selected wavelength, and a probe, for example, a probe of a scanned-proximity probe microscope, to which the light-sensitive molecule is attached. A method of making the molecular manipulator includes covalently bonding the light-sensitive molecule to the probe. A method of moving a nanostructure includes controllably grasping, moving, and releasing the nanostructure with the molecular manipulator.
摘要:
The present invention provides a substrate having thereon a patterned small molecule organic semiconductor layer. The present invention also provides a method and a system for producing a substrate having thereon a patterned small molecule organic semiconductor layer. The substrate having thereon a patterned small molecule organic semiconductor layer is produced by exposing a donor substrate having thereon a small molecule organic semiconductor layer to energy to cause the thermal transfer of a small organic molecule onto an acceptor substrate.

A method of making a large single crystal thin film not dependent upon the size or temperature resistance of the substrate crystal by first depositing an amorphous film of the crystalline material to be produced followed by heating of the amorphous film in such a manner that nucleation of epitaxial grains is propagated through the amorphous film whereby a single crystal thin film is produced.

A liquid crystal display device has first and second substrates, a first electrode layer overlying one surface of the first substrate, and a second electrode layer overlying one surface of the second substrate. A first alignment layer having a thickness of 100 Å or less overlies the first electrode layer, and a second alignment layer overlies the second electrode layer, and a liquid crystal material is disposed between the alignment layers. In one preferred embodiment, the second alignment layer also has a thickness of 100 Å or less, and each alignment layers is a polyimide layer. A method for manufacturing a liquid crystal display device is also provided. According to the method, first and second substrates are provided, a first electrode layer is deposited over the first substrate, and a second electrode layer is deposited over the second substrate. A first alignment layer having a thickness of 100 Å or less is deposited over the first electrode layer, and a second alignment layer is deposited over the second electrode layer. Additionally, the first and second substrates are arranged so that the alignment layers face one another and a space is formed between the substrates. A liquid crystal material is disposed in the space between the first and second substrates.
