摘要：
Ultrafast terahertz spectroscopy is an important tool for exploring new materials, yet unravelling some phenomena requires ultrafast experiments with atomic resolution such as terahertz scanning tunneling microscopy (THz-STM). Here, we advance THz-STM as a diagnostic technique for materials science by demonstrating terahertz scanning tunneling spectroscopy (THz-STS) with atomic spatial resolution and introduce an algorithm for extracting the underlying differential conductance from THz-STS measurements in both steady-state and pump-probe scenarios.
