Spatiotemporal Terahertz Emission Nanoscopy of Spintronic Photocurrents
F. Paries, R. Rouzegar, J. Cai +9
Capturing ultrafast spin and charge photocurrents on nanoscopic scales is essential for fundamental research in physics and engineering, as well as for future applications, such as…
Mach-Zehnder based Rotational Shearing Interferometer for Non-destructive Testing using Spatial Phase-Shifting Shearography
Valentin-Johannes Bastgen, Michael Schuth, Georg von Freymann
This work introduces a novel optical setup based on a Mach-Zehnder interferometer, enabling spatial phase shifting shearography with rotational shear. The optical concept employs a…
Accessibility of doping ranges of semiconductors by terahertz spectroscopy
Joshua Hennig, Jens Klier, Stefan Duran +4
While established semiconductor measurement techniques such as four-point probe or capacitance-voltage measurements require a physical contact to the material, terahertz spectrosco…
Terahertz-Induced Nonlinear Response in ZnTe
Felix Selz, Johanna Kölbel, Felix Paries +3
Measuring terahertz waveforms in terahertz spectroscopy often relies on electrooptic sampling employing a ZnTe crystal. Although the nonlinearities in such zincblende semiconductor…
