太赫兹时域光谱允许在不同范围的二维半导体异质结构中检查电荷的相干运动。综述了二维量子系统的太赫兹电导率和磁导率的研究，包括回旋共振谱和霍尔区和量子霍尔区的横向电导率。描述了在太赫兹频率下演示量子现象的实验，主要是电磁腔中的相干控制和增强的光-物质耦合。
Terahertz time-domain spectroscopy permits the coherent motion of charges to be examined in a diverse range of two-dimensional semiconductor heterostructures. Studies of the THz conductivity and magnetoconductivity of two-dimensional quantum systems are reviewed, including cyclotron resonance spectroscopy and the transverse conductivity in the Hall and quantum Hall regimes. Experiments are described that demonstrate quantum phenomena at THz frequencies, principally coherent control and enhanced light–matter coupling in electromagnetic cavities.
