Abstract:
A vanadium dioxide (VO 2 )-based threshold switch device exhibiting current-controlled negative differential resistance (S-type NDR), an electrical oscillator circuit based on the threshold switch device, a wafer including a plurality of said devices, and a method of manufacturing said device are provided. The VO 2 -based threshold switch device exhibits volatile resistance switching and current-controlled negative differential resistance from the first time a sweeping voltage or voltage pulse is applied across the device without being treated with an electroforming process. Furthermore, the device exhibits substantially identical switching characteristics over at least 10 3  switching operations between a high resistance state (HRS) and a low resistance state (LRS), and a plurality of threshold switch devices exhibits a threshold voltage V T  spreading of less than about 25%. The threshold switch device may be included in an oscillator circuit to produce an astable oscillator that may serve as a functional building block in spiking-neuron based neuromorphic computing.

Claim (Index 1):
A threshold switch device comprising:\n a complementary metal-oxide-semiconductor (CMOS)-compatible substrate; a first electrode on the CMOS-compatible substrate, the first electrode extending along a first direction; a second electrode on the first electrode, the second electrode extending along a second direction crossing the first direction; and a switching layer between the first electrode and the second electrode, the switching layer providing a first contact with the first electrode and a second contact with the second electrode at least along a thickness direction (TD) overlap of the device between the first electrode and the second electrode; the switching layer being substantially composed of polycrystalline vanadium dioxide (VO 2 ), and having no epitaxial relationship with the CMOS-compatible substrate.
