Abstract

Over the past few years, there has been a notable surge in research interest directed towards organic molecular ferroelectrics. Consequently, it is now a critical juncture to delve into the fundamental structural constraints of molecular ferroelectrics, exploring various structural parameters, thermal characteristics, and distinct dielectric properties. This review paper embarks on a comprehensive examination of organic ferroelectrics, centering its focus on diisopropylammonium halides as a representative example. Within these pages, we provide an in-depth analysis of recent advancements in the field, encompassing their ferroelectric and dielectric properties, phase transition temperatures, and the phenomenon of spontaneous polarization. These insights open up new avenues for practical applications of organic ferroelectrics in diverse domains. However, it's worth noting that within this review, we also tackle a contentious issue that arises with diisopropylammonium iodide. This controversy revolves around the determination of the actual value of polarization, a topic that is thoroughly examined and discussed.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
