Gate Engineering Effect in Ferroelectric Field‐Effect Transistors with Al‐Doped HfO2 Thin Film and Amorphous Indium‐Gallium‐Zinc‐Oxide Channel

Gate Engineering Effect in Ferroelectric Field‐Effect Transistors with Al‐Doped HfO2 Thin Film and Amorphous Indium‐Gallium‐Zinc‐Oxide Channel

Abstract This work investigates the mechanism for the memory window (MW) suppression of the ferroelectric‐thin film transistors (FETFTs) with an amorphous indium‐gallium‐zinc (a‐IGZO) channel. a‐IGZO generally has an n‐type character with a high bandgap (>3 eV) and a high density of gap states, h...
