An apparatus includes a manifold with a chamber for mixing multiple reactants. Gases are jetted into the manifold by a plurality of inlet injectors. The inlet injectors are arranged such that the gases passing into the manifold impinge on each other at a common point to form a mixture. The mixture passes through a plurality of holes in one side of the manifold into a deposition chamber where the mixture of gases impinges on additional gases at a common point to provide a reaction resulting in deposition of solid materials in the deposition chamber. The solid materials are free-standing. 1. An apparatus comprising:A manifold comprising a mixing chamber, the mixing chamber comprises a plurality of inlet injectors, each inlet injector comprises a bore opening into the mixing chamber for the introduction of gases into the mixing chamber, the bores of the plurality of inlet injectors are angled to allow the gases entering into the mixing chamber to impinge on each other in the mixing chamber;A dispersion plate covers a side of the mixing chamber, the dispersion plate comprises a plurality of holes for egress of a substantially uniform mixture of gases from the mixing chamber; andA cross-jet component joined to the manifold, the cross-jet component comprises a plurality of holes for the egress of additional gases from the cross-jet component, each hole of the cross-jet component corresponds to a hole in the dispersion plate to allow the substantially uniform mixture of gases from the mixing chamber of the manifold to impinge on the additional gases from the cross-jet component.2. The apparatus of claim 1 , wherein the manifold further comprises a confinement chamber defined by two plates each having four side and two faces claim 1 , the plates join at a common side and a top side of each plate joins a top of the manifold and a back side of each plate joins a backside of the manifold claim 1 , each face of each plate comprises a hole for insertion of an inlet injector.3. ...
