Terahertz waveforms can now be measured with atomic-scale spatial resolution as a result of a new form of terahertz time-domain spectroscopy that uses tunnelling electrons as an ultrafast, localized probe. The approach paves the way for ultrafast optical surface analysis at the scale of individual molecules or atoms.

将时域光谱缩小到原子维度


由于采用隧道电子作为超快局部探针的新型太赫兹时域光谱，现在可以以原子级空间分辨率测量太赫兹波形。该方法为单个分子或原子尺度的超快光学表面分析铺平了道路。
