International Classification:

C30B 23/00

US Classification:

117 9, 117 4, 117 8, 117108, 117109, 117952

Abstract:

A method of fabricating an SiC single crystal includes (a) physical vapor transport (PVT) growing a SiC single crystal on a seed crystal in the presence of a temperature gradient, wherein an early-to-grow portion of the SiC single crystal is at a lower temperature than a later-to-grow portion of the SiC single crystal. Once grown, the SiC single crystal is annealed in the presence of a reverse temperature gradient, wherein the later-to-grow portion of the SiC single crystal is at a lower temperature than the early-to-grow portion of the SiC single crystal.

US Classification:

428 641, 117 84, 118720, 125 3001

Abstract:

A method and system of forming large-diameter SiC single crystals suitable for fabricating high crystal quality SiC substrates of 100, 125, 150 and 200 mm in diameter are described. The SiC single crystals are grown by a seeded sublimation technique in the presence of a shallow radial temperature gradient. During SiC sublimation growth, a flux of SiC bearing vapors filtered from carbon particulates is substantially restricted to a central area of the surface of the seed crystal by a separation plate disposed between the seed crystal and a source of the SiC bearing vapors. The separation plate includes a first, substantially vapor-permeable part surrounded by a second, substantially non vapor-permeable part. The grown crystals have a flat or slightly convex growth interface. Large-diameter SiC wafers fabricated from the grown crystals exhibit low lattice curvature and low densities of crystal defects, such as stacking faults, inclusions, micropipes and dislocations.

Abstract:

The present invention relates to the field of viral gene therapy. More specifically, A the present invention provides compositions and methods for retargeting virus constructs. In one embodiment, the present invention provides an adenoviral construct comprising a nucleic acid encoding the peptide sequence MAE-X-PDP, wherein X is an antigen targeting peptide. In a more specific embodiment, an adenoviral construct comprises a nucleic acid sequence encoding the peptide sequence MAEWQPDTAHHWALTLPDP inserted into the HI-loop of adenovirus fiber protein. In yet another embodiment, the present invention provides a method for optimizing adenoviral infection of target cells comprising the steps of (a) generating a peptide-display adenovirus library, wherein the displayed peptide is a peptide that specifically binds an antigen expressed on the surface of a target cell, and wherein the displayed peptide is flanked by random peptide sequences; and (b) screening the peptide-display adenovirus library against the target cells.

Abstract:

In a crystal growth apparatus and method, polycrystalline source material and a seed crystal are introduced into a growth ambient comprised of a growth crucible disposed inside of a furnace chamber. In the presence of a first sublimation growth pressure, a single crystal is sublimation grown on the seed crystal via precipitation of sublimated source material on the seed crystal in the presence of a flow of a first gas that includes a reactive component that reacts with and removes donor and/or acceptor background impurities from the growth ambient during said sublimation growth. Then, in the presence of a second sublimation growth pressure, the single crystal is sublimation grown on the seed crystal via precipitation of sublimated source material on the seed crystal in the presence of a flow of a second gas that includes dopant vapors, but which does not include the reactive component.
