Time-resolved, pulsed terahertz spectroscopy has developed into a powerful tool to study
charge carrier dynamics in semiconductors and semiconductor structures over the past …

We review pioneering and recent studies of the conductivity of solid state systems at
terahertz frequencies. A variety of theoretical formalisms that describe the terahertz …

Terahertz time-domain spectroscopy is used to measure the complex conductivity of
nanometer-thick gold films evaporated on silicon substrates in the far-infrared spectral …

The Drude-Smith model has been used extensively in fitting the THz conductivities of
nanomaterials with carrier confinement on the mesoscopic scale. Here, we show that the …

We investigate the dielectric properties of a thin VO 2 film in the terahertz frequency range in
the vicinity of the semiconductor-metal phase transition. Phase-sensitive broadband …

Silicon quantum dots (SiQDs) hold great promise for many future technologies. Silicon is
already at the core of photovoltaics and microelectronics, and SiQDs are capable of efficient …

We demonstrate a combination of micro four-point probe (M4PP) and non-contact terahertz
time-domain spectroscopy (THz-TDS) measurements for centimeter scale quantitative …

Generation of high‐power radiation in terahertz frequency range 0.3–10 THz is a fast
develo** research area attracting considerable interest over the past years due to its …

The time-resolved conductivity of isolated GaAs nanowires is investigated by optical-pump
terahertz-probe time-domain spectroscopy. The electronic response exhibits a pronounced …
