Terahertz Time Domain Spectroscopy

In this work we illustate principles and technical aspects of a typical THz TDS setup, including the demonstration of a Co/Pt thin film calibrant measurements.

Time-Domain terahertz spectroscopy (THz TDS) has attracted attention from many scientific disciplines as it enables accessing the gap between electronic and optical techniques. One application is to probe spintronic dynamics in sub-picosecond time scale. Here, we discuss principles and technical aspects of a typical THz TDS setup. We also show an example of terahertz time-domain data obtained from a Co/Pt thin film calibrant, which is a well-studied spintronic structure emitting strong THz radiation.
