title = "Superlattice HfO2-ZrO2based Ferro-Stack HfZrO2FeFETs: Homogeneous-Domain Merits Ultra-Low Error, Low Programming Voltage 4 V and Robust Endurance 109cycles for Multibit NVM",
abstract = "Superlattice (SL) HfO2-ZrO2 with physical thickness of 5 nm and low phase fraction ratio 0.101:1 of monoclinic-phase (m-phase) to orthorhombic-phase (o-phase) investigated by geometrical phase analysis (GPA) is demonstrated. The homogeneous and congruous of SL-HfZrO2 (HZO) with sufficient ferroelectric-domain is integrated as ferro-stack FeFETs for multibit NVM with low |VPG/ER| = 4 V, ultra-low error rate = 7.5×10-16, record high 2-bit endurance for 109 cycles, and stable data retention > 104 s. The device-to-device (D2D) variation of nanoscale 3D FeFETs is also improved with the proposed SL-HZO. The superlattice technique for FE-HZO is a promising concept with elevating the coherence of domain access due to high o-phase toward emerging memory applications.",
