Ferroelectric Electron Holography [PDF]
Microscopy and Microanalysis, 2002 Ferroelectrics are increasingly important as materials in semiconductor technology, e.g. for building non-volatile memory chips. For optimisation of the properties of such devices, there is an urgent need for methods, which analyse the ferroelectric properties at nanometer scale. Furthermore, the basic understanding of the interaction of ferroelectrics

Ferroelectricity enhancement in ferroelectric nanotubes [PDF]
Phase Transitions, 2007 In this paper we study the size effects of the ferroelectric nanotube phase diagrams and polar properties allowing for effective surface tension and depolarization field influence. The approximate analytical expression for the paraelectric-ferroelectric transition temperature dependence on the radii of nanotube, polarization gradient coefficient ...

Ferroelectric Dead Layer Driven by a Polar Interface [PDF]
, 2010 Based on first-principles and model calculations we investigate the effect of polar interfaces on the ferroelectric stability of thin-film ferroelectrics. As a representative model, we consider a TiO2-terminated BaTiO3 film with LaO monolayers at the two

Electrode materials based on Micro-emulsion Polymerized Polyaniline and Their Capacitive Property
International Journal of Electrochemical Science, 2019 The conductive polyaniline (PANI) electrode materials with different morphologies were prepared by micro-emulsion polymerization with dodecylbenzene sulfonic acid (DBSA) as the dopant and surfactant, and ammonium persulfate (APS) as the oxidant.

Ferroelectric Polarization Enhancement in Hafnium-Based Oxides Through Capping Layer Engineering
IEEE Journal of the Electron Devices Society, 2022 In this work, we investigate that the capping layer (CL) engineering of aluminum oxide (AlOx) on the dopant-free hafnium oxide (HfOx) and the hafnium zirconium oxide (HfZrOx) ferroelectric metal-ferroelectric-metal (MFM) capacitors. The AlOx CL featuring
