Abstract: An MOCVD system fabricates high quality superconductor tapes with variable thicknesses. The MOCVD system can include a gas flow chamber between two parallel channels in a housing. A substrate tape is heated and then passed through the MOCVD housing such that the gas flow is perpendicular to the tape's surface. Precursors are injected into the gas flow for deposition on the substrate tape. In this way, superconductor tapes can be fabricated with variable thicknesses, uniform precursor deposition, and high critical current densities.

Abstract: An ultra-thin film superconducting tape and method for fabricating same is disclosed. Embodiments are directed to a superconducting tape being fabricated by processes which include removing a portion of the superconducting tape's substrate subsequent the substrate's initial formation, whereby a thickness of the superconducting tape is reduced to 15-80 μm.

Abstract: A superconductor tape and method for manufacturing, measuring, monitoring, and controlling same are disclosed. Embodiments are directed to a superconductor tape which includes a superconductor film overlying a buffer layer which overlies a substrate. In one embodiment, the superconductor film is defined as having a c-axis lattice constant higher than 11.74 Angstroms. In another embodiment, the superconductor film comprises BaMO3, where M=Zr, Sn, Ta, Nb, Hf, or Ce, and which has a (101) peak of BaMO3 elongated along an axis that is between 60° to 90° from an axis of the (001) peaks of the superconductor film. These and other embodiments achieve well-aligned nanocolumnar defects and thus a high lift factor, which can result in superior critical current performance of the tape in, for example, high magnetic fields.

Abstract: A superconductor tape may be fabricated via Metal Organic Chemical Vapor Deposition (MOCVD) to achieve peel strengths greater than approximately 4.5 N/cm. The superconductor tape may be fabricated via MOCVD with a REBCO composition that includes the elements Samarium (Sm)-Barium(Ba)-Copper(Cu)-Oxygen(O). Varying levels of Copper (Cu) content can achieve peel strengths ranging between approximately 4.5 N/cm to approximately 8.0 N/cm.
