太赫兹科学与技术研究回顾
Materials for terahertz science and technology

摘要: 太赫兹光谱系统利用远红外辐射获得分子的某些光谱信息,这些信息在电磁谱的其他波段中是很难得到的.材料的研究是现代太赫兹系统中的重要的组成部分,一方面因为新的、大功率的太赫兹光源极大地依赖于如量子级联结构一类的新材料;另一方面,太赫兹的光谱和成像技术也为扩展诸如半导体和生物有机分子等材料的应用提供了一个有力的工具.Abstract: Terahertz spectroscopy systems use far-infrared radiation to extract molecular spectral information in an otherwise inaccessible portion of the electromagnetic spectrum. Materials research is an essential component of modern terahertz systems; novel, higher-power terahertz sources rely heavily on new materials such as quantum cascade structures. At the same time, terahertz spectroscopy and imaging provide a powerful tool for the characterization of a broad range of materials, including semiconductors and biomolecules.
