Abstract:
1. A method of producing an electrochemical sensor with a detector zone, the method which comprises: providing a substrate and feeding a number of precursor substances in gaseous form to a deposition zone in a vicinity of a substrate; energetically exciting the precursor substances for converting the precursor substances to form conversion products and causing the energetically excited conversion products to deposit in solid and nonvolatile form on the substrate, to thereby form the detector zone with an electrical conductivity determined by electron tunneling, ionization, or hopping processes and configured for detecting an electrochemical interaction thereof with a target substance to be detected by the electrochemical sensor; and setting a plurality of process parameters so that the detector zone has a predetermined electrical conductivity dependent on a temperature T that is approximately governed by the relationship ln σ˜T
