A ferroelectric memristor [PDF]
Nature Materials, 2012 Memristors are continuously tunable resistors that emulate synapses. Conceptualized in the 1970s, they traditionally operate by voltage-induced displacements of matter, but the mechanism remains controversial. Purely electronic memristors have recently emerged based on well-established physical phenomena with albeit modest resistance changes.

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 ...

The Rise of Ferroelectricity at Nanoscale: Nanoelectronics is rediscovering the ferroelectricity
IEEE Nanotechnology Magazine, 2021 We present a comprehensive review of the emerging nanoscale ferroelectric materials used in novel nanoelectronics devices. First, we outline specific physical and electronic properties of ferroelectric materials, then we focus on two main classes of ferroelectrics based on hafnium oxide (HfO2) and 2D materials.

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
