a Schematics and b TEM image of an HZO(Hf0.5Zr0.5O2)-CAP under tests. The thickness of HZO is 6 nm. c The evolution of P–V characteristics from AFE-like double hysteresis to FE-like single one observed in the HZO-CAP before 106 polarization switching cycling. d The corresponding evolution of energy landscape of the HZO-CAP before 106 polarization switching cycling, fitted from the I–V and P–V curves using LGD model. eP–E characteristic of the HZO-CAP just after 106 polarization switching cycling fitted by LGD model. f Corresponding energy landscape of the HZO-CAP just after 106 polarization switching cycling and its TFE switching pathway fitted by LGD model.
