Voltage-controlled switches

摘要

A voltage-controlled switch comprises a first electrode, a second electrode, a switching junction situated between the first electrode and the second electrode, a conducting channel extending from adjacent to the origin through the switching junction and having a channel end situated near the second electrode, and a layer of dopants situated adjacent to an interface between the switching junction and the second electrode, wherein the dopants are capable of being activated to form switching centers.

1. A voltage-controlled switch, comprising:
a first electrode; a second electrode; a switching junction situated between the first electrode and the second electrode; a conducting channel having an origin adjacent to the first electrode and extending through the switching junction, and having a channel end situated near the second electrode; and dopants in the switching junction situated adjacent to an interface between the switching junction and the second electrode, the dopants being switching centers that are capable of being activated to conduct electricity, the dopants and the switching junction comprising different chemical elements; wherein the switch is in a first state when a first number of the switching centers are active and conductive, and the switch is in a second state when a second number of the switching centers are active and conductive, the second number of the switching centers being greater than the first number of the switching centers so the second state is more conductive than the first state.
