β-Bi2SeO5/Bi2O2Se Heterostructure

Self-rectifying memristor with sub-pA sneak current

A quasi-free-standing Bi2O2Se single-crystalline film is layer-controlled oxidized to form a self-rectifying heterostructure memristor with ultrafast switching and low power consumption, promising for high-density crosstalk-free arrays.
