Abstract
An emitter is disclosed. The emitter includes a base layer comprising an array of nanocavities on an emission surface of the base layer, wherein facets of the nanocavities are substantially along equivalent crystallographic planes of one or more families of planes having substantially equal surface energies, wherein the equivalent crystallographic planes have surface energies equal to or lower than a surface energy of the crystallographic plane of the emission surface. Methods of making such emitters and radiation sources including such emitters are also disclosed.
