Threshold switching in Si-As-Te thin film for the selector device of crossbar resistive memory
Threshold-switching (TS) and selector performances of Si-As-Te thin films for crossbar resistive memory were studied. Composition of the film was the major factor determining the emergence of TS. On-state conduction was found to occur at localized regions. The change of threshold voltage and off-sta...

Composition of the film was the major factor determining the emergence of TS. On-state conduction was found to occur at localized regions. The change of threshold voltage and off-state current by varying composition was observed, which were explained by the change in the concentration of defects and generation efficiency of carriers.
