SELECTOR DEVICES INCLUDING S-DOPED AsSeGeSi CHALCOGENIDES

Abstract:

A switching device having a first electrode, a second electrode, and a switching layer between the first and second electrodes, formed using a chalcogenide composition doped with an element that suppresses oxidation, which results in improved manufacturability and yield. For selector material based on AsSeGeSi or other chalcogenide materials that include selenium or arsenic, or other chalcogenide materials that include selenium or arsenic and silicon, the element added to suppress oxidation can be sulfur.
