摘要

Ferroelectric tunnel junction (FTJ) with ultrathin 3 nm-thick Hf0.5Zr0.5O2 (HZO) is investigated. The high current density up to 100 A/cm2 is at least 10 times higher than that in previously reported HZO FTJs. It is suitable for future nanoscale FTJ with a GΩ cell resistance for the application of in-memory computing. The insertion of a thin Al2O3 interfacial layer is found critical to alter the switching polarity and increase current density.
