THz imaging and microscopy, a multiplexed near-field TeraHertz microscope
… This spatial modulator can also be employed for Far-Infrared spectroscopy, resulting in a functional THz imaging-spectroscopy system. The THz modulators optoelectronic performance was thoroughly examined in medium-, long-wave infrared, and THz regimes. This project results in a first ever fully …

Synchrotron radiation-based characterization of GaN- based MQW structures and strongly correlated materials
… types within the film volume. Synchrotron-based far-infrared spectroscopy was performed at low temperatures on the single crystal multiferroic manganite HoMn_2O_5. A number of the infrared-active excitations were attributed to electric-dipole transitions between ligand-field split states of …

Kopplung von kollektiven Anregungen in einlagigen und doppellagigen quasi-zweidimensionalen Elektronensystemen
Gegenstand dieser Arbeit ist die Kopplung von kollektiven Anregungen in einlagigen und doppellagigen quasi-zweidimensionalen Elektronensystemen. Es wurden verschiedene modulationsdotierte Proben auf Basis von GaAs mit Gate-Elektrode und Gitterkoppler präpariert, um bei variabler Elektronendichte …

Broadband THz time-domain spectroscopy of biomolecules : a comprehensive study of the dielectric properties of biomaterials in the far-infrared
Since the introduction of THz-time-domain spectroscopy (THz-TDS) in the late 1980's, the technique, based on the generation and detection of subpicosecond terahertz pulses, has found widespread use as a simple and versatile experiment technique for obtaining the low frequency response of gases, …
