Claim 0:
1. A method for chemical vapour deposition on a substrate, the method comprising
a precursor step and a reactant step,
wherein the precursor step comprises chemisorbing a layer of precursor molecules on the substrate, and
wherein the reactant step comprises adding to at least part of the substrate surface a reducing species able to reduce the precursor molecule, wherein at least a part of the chemisorbed precursor molecules are reduced and a film is deposited on the substrate surface,, wherein a positive bias is applied to at least part of the substrate surface during at least part of the reactant step by a voltage source,

wherein the step of adding the reducing species comprises providing electrons as free particles by an electron source, and
wherein a closed electrical circuit is formed during the reactant step as the free electrons are transmitted to the substrate surface.
