英国的研究人员研制出了一种全半导体室温太赫兹时域光谱仪。这是室温太赫兹时线光谱仪首次实现全半导体结构,它比传统基于超快激光器设计的太赫兹光谱仪具有成本低和体积小的优点。 British researchers have developed a full-range semiconductor THz time-domain spectrometer. This is the first time that a room temperature terahertz time-line spectrometer has achieved a full semiconductor structure, which is less costly and less bulky than a conventional terahertz-based ultrafast laser designed spectrometer.
