FIG. 1.

(Color online) The schematic band diagrams of ferroelectric diodes under short circuit conditions in the case of non-polarization (NP) (a), right polarization (RP) (b), and left polarization (LP) (c). The arrow denotes the direction of the polarization. is the polarization charge; and are the left and right barrier heights, respectively.

FIG. 2.

(Color online) The band diagrams in the case of NP, RP, and LP under short circuit conditions (a). The electron density distributions in the cases of NP, RP, and LP (b). The green dashed line denotes the doping density. The electron density distributions in the case of NP, RP, and LP in the left (c) and right (d) metals. The calculated I–V curves in the case of NP, RP, and LP (e).

FIG. 3.

(Color online) The band diagrams (a), the electron density distributions (b), and the calculated I–V curves (c) for various doping densities 1016, 1017, and 1018 cm−3 in the case of RP (a). The dashed lines denote the doping densities. The ON/OFF ratio as a function of the doping density in the ferroelectric film (d).

Image of FIG. 4.
FIG. 4.

(Color online) The band diagrams (a), the electron density distributions (b), and the calculated I–V curves (c) for various permittivity 50, 100, and 400 in the case of RP. The green dashed lines denote the doping densities. The ON/OFF ratio as a function of the permittivity in the ferroelectric film (d).

FIG. 5.

(Color online) The band diagrams (a), the electron density distributions (b), and the calculated I–V curves (c) for various thicknesses 120, 240, and 360 nm in the case of RP. The green dashed lines denote the doping densities. The ON/OFF ratio as a function of the thickness in the ferroelectric film (d).
