二维材料中的集体激发

Collective Excitations in 2D Materials

Aleksandr Rodin, Maxim Trushin, Alexandra Carvalho, A. H. Castro Neto

摘要:

二维材料的研究是近10年来凝聚态物理和材料科学发展最快的领域之一。二维系统的低维度和强相关性以集体激发的形式产生了电子和结构性质,这在现代技术中使用的普通三维材料中没有对应物。这些2D材料为新技术提供了非凡的机会,例如柔性电子产品。在这篇综述中,我们重点介绍了二维材料中的等离子体激元、激子、声子和磁振子。我们讨论了这些集体激发的理论形式主义,并阐明他们如何不同于他们的3D同行。

英文摘要:

Research on 2D materials has been one of the fastest-growing fields in condensed matter physics and materials science in the past 10 years. The low dimensionality and strong correlations of 2D systems give rise to electronic and structural properties, in the form of collective excitations, that do not have counterparts in ordinary 3D materials used in modern technology. These 2D materials present extraordinary opportunities for new technologies, such as in flexible electronics. In this Review, we focus on plasmons, excitons, phonons and magnons in 2D materials. We discuss the theoretical formalism of these collective excitations and elucidate how they differ from their 3D counterparts.
