Schematics of various steps involved in the fabrication of voltage-gated vermiculite samples for studying gated ion transport characteristics. Here, h, w, and l are the thickness, width, and length of the membrane, respectively. We used a gold wire to apply the gate voltage. The images are not drawn to scale.
