Time-resolved THz Stark spectroscopy
Bong Joo Kang, Egmont J. Rohwer, David Rohrbach +12
We introduce THz Stark spectroscopy by using intense single-cycle terahertz pulses as the electric field source and monitoring the induced spectral response of an isotropic molecul…
Wideband dispersion-free THz waveguide platform
David Rohrbach, Bong Joo Kang, Elnaz Zyaee +1
We present an integrated THz spectroscopy and sensing platform featuring low loss, vacuum-like dispersion, and strong field confinement in the fundamental mode. Its performance was…
Structure, Organization and Heterogeneity of Water-Containing Deep Eutectic Solvents
Kai Töpfer, Andrea Pasti, Anuradha Das +6
The spectroscopy and structural dynamics of a deep eutectic mixture (KSCN/acetamide) with varying water content is investigated from 2D IR (with the C-N stretch vibration of the SC…
Metastable defects decrease the fill factor of solar cells
Thomas Paul Weiss, Omar Ramírez, Stefan Paetel +4
Cu(In,Ga)Se2 based solar cells exceed power conversion efficiencies of 23 %. Yet, the fill factor of these solar cells, with best values around 80 %, is relatively low (Si reaches…
