NANOSCALE SWITCHING DEVICE WITH AN AMORPHOUS SWITCHING MATERIAL

摘要

Nanoscale switching devices are disclosed. The devices have a first electrode of a nanoscale width; a second electrode of a nanoscale width; and a layer of an active region disposed between and in electrical contact with the first and second electrodes. The active region contains a switching material capable of carrying a significant amount of defects which can trap and de-trap electrons under electrical bias. The switching material is in an amorphous state. A nanoscale crossbar array containing a plurality of the devices and a method for making the devices are also disclosed.
