Abstract:
1. An electrical bistable device comprising: an electrically conductive mixed layer comprising a first side and a second side, said mixed layer comprising a low conductivity material and a high conductivity material wherein said mixed layer is electrically conductive; a first layer of low conductivity material located on said first side of said mixed layer, said first layer of low conductivity material having a first electrode side; a second layer of low conductivity material located on said second side of said mixed layer, said second layer of low conductivity material having a second electrode side; a first electrode attached to said first layer of low conductivity material at said first electrode side; a second electrode attached to said second layer of low conductivity material at said second electrode side; a first interface located on the first side of said mixed layer where said first layer of low conductivity material and said mixed layer meet, said first interface being electrically convertible between a stable low resistance state and a stable high resistance state by application of an electrical voltage between the said first electrode and said mixed layer; a second interface located on the second side of said mixed layer where said second layer of low conductivity material and said mixed layer meet, said second interface being electrically convertible between a stable low resistance state and a stable high resistance state by application of an electrical voltage between the said second electrode and said mixed layer; a first terminal in electrical connection with said first electrode; a second terminal in electrical connection with said second electrode; and a third terminal in electrical connection with said electrically conductive mixed layer, wherein said stable low resistance states and said stable high resistance states persist free from an applied voltage to provide electrical bistability.
