Abstract
A method of forming one of a plurality of encapsulated crystalline particles includes feeding a coaxial feed wire downwardly such that a first wire end of the coaxial feed wire is positioned at a heating source. The coaxial feed wire includes a crystalline wire core, and an amorphous shell surrounding the crystalline wire core. The first end of the coaxial feed wire is heated at the heating source, thereby forming a molten pendant drop at the first wire end. The plurality of encapsulated crystalline particles are emitted from the molten pendant drop onto a collector located below the molten pendant drop.

An apparatus for depositing forming one of a plurality of encapsulated crystalline particles, comprising:
- a coaxial feed wire, comprising:
- a crystalline wire core;
- and
- an amorphous shell surrounding the crystalline wire core;
- a heating source at which a first wire end of the coaxial feed wire is positioned;
- and
- a collector disposed below the heating source;
- wherein heating of the first wire end at the heating source forms a molten pendant drop at the first wire end from which a plurality of encapsulated crystalline particles are emitted onto the collector;
- and
- a pressure controlled chamber at which the coaxial feed wire is disposed upstream of the heating source.
