In this paper, the extraction of doping profiles in ferroelectric thin-film capacitors using ferroelectric capacitance–voltage (CV) measurements is studied. For a ferroelectric field-dependent permittivity model, the doping profile relation to meas

A domain model consistent with the measured capacitance–voltage (CV) characteristics of lead zirconate titanate (PZT) capacitors is proposed. Two variants of this model are presented and compared with experimentally measured CV data. The basic mode

The electric‐field distribution in a ferroelectric capacitor often is treated as a uniform effective field for circuit‐level modeling. By solving Poisson’s equation and treating the ferroelectric capacitor as a back‐to‐back Schottky‐barri

The field-dependent polarization model is a commonly proposed model to describe the hysteresis loop of a ferroelectric material. The electric field in the model refers to the local field which varies with position within the ferroelectric film. Howev

Ferroelectric thin film capacitors (FTFCs) are the basic storage element in ferroelectric memory cells. In this paper, the effects of varying film thickness and niobium doping level on electrical properties for memory applications in FTFCs are examin
