Abstract

Nonvolatile three-terminal operation, with a very small range of bias sweeping (-80 to 250 mV), a high on/off ratio of up to six orders of magnitude, and a very small gate leakage current (<1 pA), is demonstrated using an Ag (gate)/Ta2 O5 (ionic transfer layer)/Pt (source), Pt (drain) three-terminal atomic switch structure.
