Claim:
1. A method for depositing a nitride, carbide or alloy thin film comprising one or more noble metals on a substrate, the method comprising a deposition cycle comprising, in order: contacting the substrate with a first vapor phase metal reactant comprising a first metal, wherein the vapor phase metal reactant does not comprise a noble metal, such that first reactant species adsorb on the substrate surface; removing excess first vapor phase metal reactant; contacting the substrate with a second vapor phase noble-metal reactant comprising a second metal that is a noble metal, such that the second reactant reacts with adsorbed first reactant species on the substrate; and removing excess second noble-metal reactant, wherein the deposition cycle forms a monolayer of a nitride, carbide or alloy compound comprising the first metal and second metal and is repeated to form the thin film.
