Abstract: 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.
