摘要
A tunable resistance system includes a layer of a first functional material deposited on a component of the system. The first functional material undergoes a phase transition at a first critical voltage. An insulating layer is deposited upon the layer of first functional material. A layer of a second functional material deposited on the insulating layer. The second functional material undergoes a phase transition at a second critical voltage. The insulating layer is configured to induce a stress on the layer so as to change the first critical voltage. In this way, the resistance of the system is tunable, allowing the system to undergo multi-stage electrical switching of resistive states.
