A reaction system is disclosed that may be used to prevent formation of contaminants. The reaction system includes a showerhead that may be configured with a gated nanochannel grid to prevent particular gaseous precursors from passing through depending on whether a voltage is applied. The gated nanochannel grid may allow for both polar and non-polar molecules to pass, or may be configured to allow just non-polar or just polar molecules to pass.
