Abstract

The ICR (ionic current rectification) phenomenon in nanopores is influenced by both the shape and material of the nanopore, as well as the ion concentration within the electrolyte that permeates the nanopore. Specifically, nanopores composed of multiple materials can induce ICR due to variations in ion distribution along the nanopore-electrolyte interface across different sections of the material. In this study, we investigate the impact of configurations involving up to two layers of different materials (Si₃N₄ and Au) and six different electrolytes on solid-state nanoporous ICR. We aim to assess how different configurations of surface charges can influence ICR. The main advantage of nanopores made from gold and other metals may be their use as an ICR amplifier when illuminating nanopores with a wavelength of light lying in the plasmon resonance region of the metal used.
