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.

A method of forming one of a plurality of particles, comprising:
- feeding a microwire such that a first wire end of the microwire is disposed at a heating source;
- heating the first end of the microwire at the heating source, thereby forming a molten pendant drop at the first wire end;
- positioning a flow of sheath gas around the microwire upstream of the heating source;
- and
- emitting the plurality of particles from the molten pendant drop;
- wherein the microwire includes:
- a crystalline wire core;
- and
- an amorphous shell surrounding the crystalline wire core.
