Switchable two-terminal devices with diffusion/drift species |
| 摘要 |
Various embodiments of the present invention are directed to nanoscale electronic devices that provide nonvolatile memristive switching. In one aspect, a two-terminal device (600) comprises a first electrode (602), a second electrode (604), and an active region (606) disposed between the first electrode and the second electrode. The active region includes a mobile dopant (608), and a fast drift ionic species (610). The fast drift ionic species drifts into a diode-like electrode/active region interface temporarily increasing conductance across the interface when a write voltage is applied to the two-terminal device to switch the device conductance. |

1. A two-terminal device comprising:
a first electrode; a second electrode; and an active region disposed between the first electrode and the second electrode, the active region including,
a mobile dopant, anda fast drift ionic species, wherein the fast drift ionic species is to drift into an electrode/active region interface to temporarily increase conductance across the electrode/active region interface when a write voltage is applied to the two-terminal device to switch from a high-conductance state to a low-conductance state. |
