Abstract

Highly textured [111] oriented films such as MgO crystalline films are deposited by e-beam evaporation on ordinary soda-lime glass. Semiconductor films such as silicon can be deposited on these MgO films using eutectics at temperatures below the softening point of ordinary glass and having extremely high textured and strong [111] orientation. The invention may be used for efficient and cost effective solar cells, displays, etc.

Abstract

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.

Abstract

The present invention concerns the enhancement of critical current densities in cuprate superconductors. Such enhancement of critical current densities include using wave function symmetry and restricting movement of Abrikosov (A) vortices, Josephson (J) vortices, or Abrikosov-Josephson (A- J) vortices by using the half integer vortices associated with d-wave symmetry present in the grain boundary.
