三维拓扑绝缘体的太赫兹光电流光谱

Terahertz Photogalvanic Spectroscopy of Three Dimensional Topological Insulators

Helene Plank, Sergey D. Ganichev

摘要:

本文综述了太赫兹极化辐射在BiSbTe基三维拓扑绝缘体中引起的光电流效应的实验和理论研究。我们提出了这个问题的最先进的,包括最新的和完善的结果。我们讨论了一个唯象理论的基础上对称性参数和模型说明光电流的起源。我们简要介绍了基本的微观理论,以及主要的实验结果的概述。

英文摘要:

The paper overviews experimental and theoretical studies of photogalvanic effects induced in BiSbTe- based three dimensional topological insulators by polarized terahertz radiation. We present the state-of-the-art of this subject, including most recent and well-established results. We discuss a phenomenological theory based on symmetry arguments and models illustrating the photocurrents origin. We give a brief glimpse of the underlying microscopic theory, as well as an overview of the main experimental results.
