Ferroelectric Field-Effect-Transistor Integrated with Ferroelectrics Heterostructure.

ABSTRACT: To address the demands of emerging data-centric computing applications, ferroelectric field-effect transistors (Fe-FETs) are considered the forefront of semiconductor electronics owing to their energy and area efficiency and merged logic-memory functionalities. Herein, the fabrication and application of an Fe-FET, which is integrated with a van der Waals ferroelectrics heterostructure (CuInP₂ S₆ /α-In₂ Se₃ ), is reported. Leveraging enhanced polarization originating from the dipole coupling of CIPS and α-In₂ Se₃ , the fabricated Fe-FET exhibits a large memory window of 14.5 V at V_GS = ±10 V, reaching a memory window to sweep range of ≈72%. Piezoelectric force microscopy measurements confirm the enhanced polarizati
