Extreme Bond Ionicity in Mg─Te Chalcogenides for Ultrathin Low Voltage Selector-Only Memory beyond the Leakage Scaling Limit.
Conventional ovonic threshold switching (OTS) chalcogenides face a fundamental scaling limit for selector-only memory (SOM), because aggressive thickness scaling increases leakage current and hinders reliable low voltage operation. Here, this trade-off can be overcome by exploiting the unique materials characteristics...
