Abstract:
A switching element comprising:a first electrode layer and a second electrode layer; a switching layer including a charge transfer complex containing an electron donor and an electron acceptor between the first electrode layer and the second electrode layer; and an insulating layer contacting the switching layer between the first electrode layer and the switching layer, wherein the switching layer switches from a high-resistance state to a low-resistance state upon application of a voltage greater than a first threshold value in a first bias direction between the first electrode layer and the second electrode layer, maintaining the low-resistance state when the applied voltage decreases thereafter beyond the first threshold value, and switches from the low-resistance state to the high-resistance state upon application of a voltage greater than a second threshold value in a second bias direction or a reverse direction to the first bias direction, maintaining the high-resistance state when the applied voltage decreases thereafter beyond the second threshold value.
