Abstract
A device () with a switchable capacitance comprises a first and a second electrode () facing each other, a dielectric layer () between a first and a second capacitor electrode (), and a switching member () between the second electrode () and the dielectric layer (), the switching member () comprising a switching material reversibly switchable between a lower conductivity state and a higher conductivity state, each of the lower conductivity state and the higher conductivity state being persistent, wherein the capacitance of the device () depends on the conductivity state of the switching material.
