The micropore device was interfaced with a probe station using two probe connections (Scheme 2). The top Pd/Au electrode serves as the central electrode, linking all micropore devices through a single probe, while the second probe connects individually to the bottom electrode, enabling independent device connections. By switching between the bottom electrodes, different micropore devices can be selected. The bottom electrode region is initially insulated by an alumina layer, creating an open circuit. To establish a proper connection, the alumina coating is removed from the bottom electrode by local etching or scratching the surface to expose the metal electrode.
