Chalcogenide-based memory material, and memory device and electronic apparatus including the same

Abstract

A chalcogenide-based memory material may include a ternary semiconductor compound having a composition represented by XaY′bSec, wherein the chalcogenide-based memory material may have an ovonic threshold-switching (OTS) characteristic, and a threshold voltage of the chalcogenide-based memory material may change according to a polarity and an intensity of an applied voltage. In XaY′bSec, X≠Y, a+b+c=1, a>0.12, b>0.18, c≥0.4, and X and Y′ independently may be different ones of In, Sb, Ga, Sn, Al, Ge, Si, and P. A memory device may include the chalcogenide-based memory material. An electronic apparatus may include the memory device.
