Transition-state-theory-based interpretation of Landau double well potential for ferroelectrics (2404.13138v1)
Published 19 Apr 2024 in cond-mat.mtrl-sci, cs.SY, and eess.SY
Abstract: Existence of quasi-static negative capacitance (QSNC) was proposed from an interpretation of the widely accepted Landau model of ferroelectrics. However, many works showed not to support the QSNC theory, making it controversial. In this letter we show the Landau model when used together with transition-state-theory, can connect various models including first-principles, Landau, Preisach and nucleation limited switching while it does not predict the existence of QSNC.
