TL;DR: It is demonstrated that one fruitful approach to alter the electronic and optical properties of MXenes is to change the nature of the transition metal.

TL;DR: It is shown that nanodisks of a conductive polymer can support localized surface plasmon resonances in the near-infrared and function as dynamic nano-optical antennas, with their resonance behaviour tunable by chemical redox reactions.

TL;DR: The theoretical background and practical realization of the integrated mid-infrared, far-inf infrared, and terahertz optical Hall effect instrument are discussed, as well as acquisition of opticalHall effect data and the corresponding model analysis procedures.

TL;DR: In this paper, the authors report noncontact, optical determination of free-charge carrier mobility, sheet density, and resistivity parameters in epitaxial graphene at room temperature using terahertz and mid-infrared ellipsometry and optical-Hall effect measurements.

TL;DR: In this paper, the temperature dependence of free-charge carrier mobility, sheet density, and effective mass of a two-dimensional electron gas in a AlGaN/GaN heterostructure deposited on SiC substrate is determined using the THz optical Hall effect in the spectral range from 0.22 to 0.32 THz for temperatures from 1.5 to 300
