Fabrication of continuous ultrathin ferroelectric films by chemical solution deposition methods [PDF]

, 2008
The integration of ferroelectrics in nanodevices requires firstly the preparation of high-quality ultrathin films. Chemical solution deposition is considered a rapid and cost-effective technique for preparing high-quality oxide films, but one that has

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.

An investigation of the photocatalytic properties of lithium niobate and barium titanate [PDF]

, 2012
Efficiency of particulate semiconductors for driving photocatalytic reactions is impractically low due to the recombination of excited carriers and intermediate species at the interface.

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.

Effects of paramagnetic interactions by the partial replacement of Zn2+ ions with Cu2+ ions in lead-free zinc-based perovskite (MA)2ZnCl4 crystal by MAS NMR

AIP Advances, 2019
The growths, structures, phase transition temperatures, and molecular dynamics of mixed (MA)2Zn1-xCuxCl4 (x=0, 0.3, 0.5, 0.7, and 1) crystals were investigated to understand the effect of the random presence of paramagnetic Cu2+.

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
