Abstract
A molecular sensor includes a substrate defining a substrate plane, and a plurality of pairs of electrode sheets above or below the substrate at an angle to the substrate plane. The molecular sensor further includes a plurality of inner dielectric sheets between each electrode sheet in each pair of electrode sheets of the plurality of pairs, and an outer dielectric sheet between each pair of electrode sheets of the plurality of pairs.
