The bilayer-based Antiferroelectric Tunneling Junction (AFTJ) with ferroelectric (FE) HfZrO2 (HZO) and dielectric (DE) Al2O3 demonstrates a current ratio of >100×, a TER (tunneling electroresistance) of >50×, multilevel states, >104 sec retention, and a cycling endurance as high as 108. The concept of tunneling current through DE in an antiferroelectric (AFE) system enhances the capacity to modulate the current/TER ratio and makes the AFTJ feasible for low-power crossbar eNVM (embedded nonvolatile memory) applications.
