Tīmeklisdimensional (1D) Poisson equation coupled with Landau-Khalatnikov (LK) equation. Fig. 1 (a) shows the program flow chart of the numerical solution. In this flow, we discretize the Poisson equation by using the finite difference method (FDM) and solve it by using the monotone iterative (MI) method. Tīmeklis2024. gada 11. nov. · The Landau–Khalatnikov equation can be applied in such cases to obtain the effective bias. To determine the effects of negative capacitance, lead zirconate titanate (PZT) ferroelectric material, a ceramic material with perovskite properties, is adopted as a gate insulator.
