摘要
新型量子材料具有丰富的新奇物性,是现代凝聚态物理和材料科学研究的重要主题之一.常见的物性调控手段有很多,比如应变场、外电场、磁场、光场以及化学吸附等.其中,应变作为调节材料物性的有效手段被广泛地应用于研究中.本文对近年来发现的多种新型量子材料(拓扑材料和二维材料)进行介绍,并重点阐述本课题组在这些材料中应变效应的相关研究进展.在拓扑材料方面,主要介绍拓扑绝缘体、拓扑狄拉克半金属以及拓扑节线半金属中应变导致的拓扑相变等;在单层二硫化钼和黑磷中,对应变调节载流子输运和超导电性等研究结果进行讨论;最后对二维铁磁、铁电材料方面应变调节磁矩、电极化、居里温度以及磁光效应等问题进行了相关分析.
Novel quantum materials have been one of the most important topics in condensed matter physics due to their unique physical properties and potential applications. Many effective methods, especially for strain, have been developed to tune the properties of solid state materials. This paper systematically reviews several novel quantum materials discovered in recent years with a focus on their strain effects. Firstly, we introduce strain-induced topological phase transitions in topological materials. Secondly, we discuss the effects on electron transport in monolayer MoS2 and superconductivity in phosphorene. Finally, we analyze the tunable magnetic moment or spontaneous electrical polarization in two-dimensional ferromagnetic or ferroelectric materials.
