Abstract
An article composed of sintered particles is produced by depositing ligand-containing particles on a substrate, then scanning the substrate with an electron beam that generates sufficient surface and subsurface heating to substantially eliminate the ligands and melt or sinter the particles into a cohesive film with superior charge carrier properties. The particles are sintered or melted together to form a polycrystalline layer that is substantially ligand-free to form, for example, a film such as a continuous polycrystalline film. The scanning operation is conducted so as to heat treat a controllably localized region at and below a surface of the particles by selecting a rate of deposited energy at the region to exceed a rate of conduction away from the substrate.
