Terahertz (THz) spectra encode information on charge transport on nanoscale distances. The linear response thus provides information on charge transport in weak electric fields. Existing theoretical models range from numerical Monte-Carlo calculation

Charge transport in PrYCaCoO 3 thin films was studied experimentally by terahertz (THz) and infrared spectroscopies and by dc conductivity measurements. The metal-insulator transition is clearly visible in THz conductivity, whereas the observed weak

The dynamics of plasmons in nanoribbons of (hydrogen intercalated) quasi-freestanding single-layer graphene is studied by terahertz spectroscopy both in the steady state and upon photoexcitation by an ultrashort near infrared laser pulse. The use of

We used time-domain terahertz spectroscopy to study the dielectric properties of a KTaU3 crystal upon applied electric field at temperatures from 40 to 250 K. Tunable ferroelectrics are promising for the control of terahertz radiation and their study
