Identification of Unknown Substances by Terahertz Spectroscopy and Multivariate Data Analysis
Andreas Pohl,Andreas Pohl,Nils Deßmann,Nils Deßmann,Katja Dutzi,Heinz-Wilhelm Hübers,Heinz-Wilhelm Hübers +6 more
TL;DR: In this paper, the identification of various substances by multivariate data analysis of terahertz transmittance spectra is demonstrated by the use of a Fourier transform infrared spectrometer.
Lifetime-limited, subnanosecond terahertz germanium photoconductive detectors
N. Deßmann,S.G. Pavlov,Andreas Pohl,Nickolay Abrosimov,Stephan Winnerl,Martin Mittendorff,Martin Mittendorff,R.Kh. Zhukavin,V. V. Tsyplenkov,D.V. Shengurov,V.N. Shastin,Heinz-Wilhelm Hübers,Heinz-Wilhelm Hübers +12 more
TL;DR: In this article, the recombination times of photo-excited free charge carriers in heavily doped and highly compensated germanium are studied by a time-resolved pump-probe experiment at a frequency of ∼3 THz.

Dynamics of non-equilibrium charge carriers in p-germanium doped by gallium
Nils Deßmann,Sergey Pavlov,V. V. Tsyplenkov,E. E. Orlova,Andreas Pohl,V.N. Shastin,R.Kh. Zhukavin,S. Winnerl,Martin Mittendorff,J. M. Klopf,Nickolay Abrosimov,Harald Schneider,Heinz-Wilhelm Hübers +12 more
TL;DR: In this paper, a single-color pump-probe experiment using the free electron laser FELBE was conducted to investigate the low-temperature capture processes of non-equilibrium holes into gallium acceptors in moderately doped p-germanium.

TL;DR: In this article, a wideband zero-bias Schottky diode detector was used for monitoring synchrotron radiation, with a response time of less than 6 ps and a noise equivalent power of 10 pW Hz -1/2.

Field transients of coherent terahertz synchrotron radiation accessed via time-resolving and correlation techniques
Andreas Pohl,Alexey Semenov,Heinz-Wilhelm Hübers,Arne Hoehl,Markus Ries,Godehard Wüstefeld,Gerhard Ulm,Konstantin Ilin,P. Thoma,Michael Siegel +9 more
TL;DR: In this article, the authors evaluated the fading oscillations of the electric field in repetitive pulses of coherent synchrotron radiation in the terahertz frequency range by means of time-resolving and correlation techniques.
