Spin-resolved terahertz spectroscopy

2016 41st International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), 2016
As such, terahertz spectroscopy cannot resolve the spin structure of conducting particles. Here we introduce the spin sensitivity to terahertz spectroscopy by using the spin-valve configuration of the sample. As a result, the number density and momentum scattering time of conduction electrons in a ferromagnetic metal can be resolved according to their ...

Nonlinear terahertz spectroscopy

SPIE Proceedings, 2010
Our recent development of a simple and reliable method to generate terahertz (THz) pulses with high intensities (equivalent to high electric field amplitudes) has paved the way for nonlinear optics in the THz regime. We present experiments on bulk n-type GaAs which give new insights into phenomena like Bloch oscillations and Zener tunneling in bulk ...

Broadband Terahertz Spectroscopy

2021
Terahertz (THz) spectroscopy is a non-contact technique to probe properties and dynamics of molecules and materials in the meV energy range and picosecond timescales. This chapter describes different popular methods of generation and detection of broadband THz pulses, experimental technique, and data analysis procedures of THz time-domain and time ...
