Claim 0:
1. A method for generating patterns on a surface of a solid substrate by directed energy deposition of carbon comprising the steps of:
selecting a pattern for deposition on said surface of said solid substrate;
providing a reaction mixture comprised of a deposit precursor, a directed electromagnetic radiation apparatus, said solid substrate, and a reaction vessel;
placing the substrate and reaction mixture in the form of a gas or liquid, which is absorbed or adsorbed to the substrate, into the reaction vessel;
selectively sending directed electromagnetic radiation towards the adsorbed or absorbed reaction mixture in the reaction vessel with the directed energy emission apparatus;
causing a polymerization and/or decomposition reaction,
wherein said pattern is generated de novo on said substrate, and further wherein said selectively sending directed electromagnetic radiation step further comprising either:
inscribing said pattern with a moving point of incidence of said directed electromagnetic radiation, or
applying said preselected pattern to said substrate, wherein the form of said preselected pattern is embodied in an interference pattern of the electromagnetic waves applied to said substrate,

wherein said causing a polymerization and/or decomposition reaction step occurs with the polymerization and/or decomposition reaction localized either:
at said moving point of incidence of an electromagnetic wave, or
at points of convergence of said interference pattern of the electromagnetic waves applied to said substrate, said points of convergence determined by said applying said preselected pattern step.
