The MpD chip developed and studied here, integrates 56 devices, each with an identical structural configuration. The use of an evaporated top electrode and a specific pore size ensures a fixed contact geometry with a precise junction area, reducing uncertainty in junction current variation due to area variations between junctions and experiments. Different from top electrodes that form a mechanical contact, contact evaporation yields a larger ratio of electrically active to geometric contact area. The use of two metal contacts, including one evaporated one, also decreases the contact resistances of the protein junctions as we show elsewhere. Additionally, MpD junctions are well-suited for low-temperature transport studies. Unlike other protein junction configurations, MpD ones allow encapsulation and immersion in liquid N2 or He, providing a robust platform for investigating transport at cryogenic temperatures.
