Methods for manufacturing monocrystalline or near-monocrystalline cast materials

Stoddard, Nathan G

Title: Methods for manufacturing monocrystalline or near-monocrystalline cast materials

Abstract

Methods are provided for casting one or more of a semiconductor, an oxide, and an intermetallic material. With such methods, a cast body of a monocrystalline form of the one or more of a semiconductor, an oxide, and an intermetallic material may be formed that is free of, or substantially free of, radially-distributed impurities and defects and having at least two dimensions that are each at least about 35 cm.
