Abstract

Crystallographic anisotropy, be it inherent or externally induced, profoundly impacts the materials’ physical properties, contributing to their ground-state morphology and magnetic arrangement and fostering distinctive optical behavior. Two-dimensional (2D) materials provide a relatively non-complex platform to study these anisotropy-driven properties. This review explores the intricate relationship between structural anisotropy and the resulting physical phenomena in 2D materials, primarily focusing on 2D hybrid perovskites (2D HPs) and transition metal phosphorous trichalcogenides. Case studies of 2D PEA2PbI4 HPs and FePS3 are provided, explaining how intrinsic structural anisotropy originates and manifests as ground state polymorphism in 2D HPs and zigzag antiferromagnetic arrangement in FePS3. The case of alloyed MnPS3 is examined, where extrinsically induced anisotropy induces magnetic disorder, impacting its magnetic phase stability and overall optical behavior. This account, thus, underscores the origin and significance of intrinsic and extrinsic anisotropy in manipulating materials’ properties.

探索二维纳米材料的结构各向异性和非调和性
晶体各向异性,无论是固有的还是外部诱导的,都深刻地影响着材料的物理性质,有助于它们的基态形态和磁排列,并形成独特的光学行为。二维(2D)材料提供了一个相对简单的平台来研究这些各向异性驱动的性质。本文探讨了二维材料中结构各向异性与由此产生的物理现象之间的复杂关系,主要集中在二维杂化钙钛矿(2D HPs)和过渡金属三硫化物磷。给出了二维PEA2PbI4 HPs和FePS3的实例研究,解释了二维HPs的固有结构各向异性是如何产生的,并表现为基态多态性和FePS3的之形反铁磁排列。研究了合金MnPS3的情况,外源诱导的各向异性导致了磁性紊乱,影响了其磁相稳定性和整体光学行为。因此,这种解释强调了内在和外在各向异性在操纵材料性质中的起源和意义。

期刊介绍: The fledgling State of Israel began to publish its scientific activity in 1951 under the general heading of Bulletin of the Research Council of Israel, which quickly split into sections to accommodate various fields in the growing academic community. In 1963, the Bulletin ceased publication and independent journals were born, with Section A becoming the new Israel Journal of Chemistry. The Israel Journal of Chemistry is the official journal of the Israel Chemical Society. Effective from Volume 50 (2010) it is published by Wiley-VCH. The Israel Journal of Chemistry is an international and peer-reviewed publication forum for Special Issues on timely research topics in all fields of chemistry: from biochemistry through organic and inorganic chemistry to polymer, physical and theoretical chemistry, including all interdisciplinary topics. Each topical issue is edited by one or several Guest Editors and primarily contains invited Review articles. Communications and Full Papers may be published occasionally, if they fit with the quality standards of the journal. The publication language is English and the journal is published twelve times a year.
