Time-resolved electronic capture in germanium doped with hydrogen-like impurity centers [PDF]

open access: yes, 2012
The capture of free holes and electrons in germanium (Ge) doped by gallium (Ga) or antimony (Sb) has been studied by a time-resolved pump-probe experiment with the free-electron laser FELBE at the Helmholtz-Zentrum Dresden-Rossendorf.

Terahertz single pixel imaging based on a Nipkow disk [PDF]

open access: yes, 2012
We describe a terahertz single pixel imaging system based on a Nipkow disk. Nipkow disks have been used for fast scanning imaging systems since the first experimental television was invented in 1926.

Compact and ultra-efficient broadband plasmonic terahertz field detector

open access: yesNature Communications, 2019
Most efficient terahertz detection schemes rely on complex free space optics and require high-power lasers. Here, the authors report an integrated plasmonic terahertz detector on a silicon photonics platform, with 2.5 THz bandwidth and a 65 dB dynamical ...
