Rare Metals, Volume 43, Issue 7, Page 3242-3249, July 2024.Graphical abstract AbstractIn this work, a conventional HfO2 gate dielectric layer is replaced with a 3‐nm ferroelectric (Fe) HZO layer in the gate stacks of advanced fin field‐effect transistors (FinFETs). Fe‐induced characteristics, e.g., negative drain induced barrier lowering (N‐DIBL) and negative differential resistance (NDR), are clearly observed
