Claims12
A molecular device comprising:
- a first electrode;
- a second electrode;
- a molecular storage layer having a large oxidized state storage layer conductivity and a low reduced state storage layer conductivity;
- and
- an electrolyte layer contacting said molecular storage layer and having a large reduced state electrolyte layer conductivity and a low oxidized state electrolyte layer conductivity, wherein said molecular storage layer and said electrolyte layer are located between said first electrode and said second electrode, said molecular storage layer connected at a first terminus to said first electrode and said electrolyte layer connected at another terminus to said second electrode, wherein said storage layer and said electrolyte layers together perform memory or logic functions using molecular electrostatic potential based on perturbing an electrostatic potential of at least one molecule within said storage layer by the movement of an ion or a localized charge proximate to said at least one molecule from said electrolyte layer.
