摘要:

能级光谱学在现代凝聚态物理中扮演着重要角色。该技术通过将固体中的电子置于量子化磁场中并进行实验探测(通常通过光学方法)来研究电子性质,特别是与能带结构相关的性质。能级光谱学能够精确提取有效质量、载流子密度、迁移率和带隙等关键参数,并作为研究固体中电子与其他准粒子相互作用的强大工具。在超过七十年的历史中,能级光谱学主要应用于半导体和半导体金属。如今,其应用范围也包括基于石墨烯的系统、拓扑材料的表面和本征态,以及其他具有窄或消失带隙的新兴系统。本文综述了能级光谱学的基本原理,并通过文献中的实例进行了说明。

英文摘要:

Landau level spectroscopy plays an important role in modern condensed-matter physics. In this technique, electrons in a solid are subjected to quantizing magnetic fields and probed experimentally, often through optical methods. Direct and detailed insights into the electronic properties of crystalline materials are obtained, particularly the properties related to their band structure. Landau level spectroscopy enables the precise extraction of key parameters such as effective mass, carrier density, mobility, and band gap, and serves as a powerful tool for studying interactions between electrons and other quasiparticles in solids. Over its more than seventy-year history, Landau level spectroscopy has been applied mainly to semiconductors and semimetals. Today, its scope also includes graphene-based systems, surface and bulk states in topological materials, and other emergent systems with a narrow or vanishing band gap. In this work, we review the fundamentals of Landau level spectroscopy and illustrate them with selected examples from the literature.
