Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

Graphene has long been predicted to show exceptional nonlinear optical properties,
especially in the technologically important terahertz (THz) frequency range. Recent …

Multiple optical harmonic generation—the multiplication of photon energy as a result of
nonlinear interaction between light and matter—is a key technology in modern electronics …

Organic-inorganic halide perovskite quantum dots (PQDs) constitute an attractive class of
materials for many optoelectronic applications. However, their charge transport properties …

In this paper, we will review both past and recent progresses in the generation, detection
and application of intense terahertz (THz) radiation. We will restrict the review to laser based …

The conversion of light into free electron–hole pairs constitutes the key process in the fields
of photodetection and photovoltaics. The efficiency of this process depends on the …

Graphene is conceivably the most nonlinear optoelectronic material we know. Its nonlinear
optical coefficients in the terahertz frequency range surpass those of other materials by …

The generation of stable trains of ultrashort (femtosecond to picosecond), terahertz-
frequency radiation pulses with large instantaneous intensities is an underlying requirement …

In its 60 years of existence, the field of nonlinear optics has gained momentum especially
over the past two decades thanks to major breakthroughs in material science and …

Evidence is accumulating for the crucial role of a solid's free electrons in the dynamics of
solid–liquid interfaces. Liquids induce electronic polarization and drive electric currents as …
