Ultra-High‑k Ferroelectric BaTiO3 Perovskite in the Gate Stack for Two-Dimensional WSe2 p‑Type High-Performance Transistors

The experimental demonstration of a p-type 2D WSe2 transistor with a ferroelectric perovskite BaTiO3 gate oxide is presented. The 30 nm thick BaTiO3 gate stack shows a robust ferroelectric hysteresis with a remanent polarization of 20 μC/cm2 and further enables a capacitance equivalent thickness of...
