We present an overview of the main techniques for production and processing of graphene
and related materials (GRMs), as well as the key characterization procedures. We adopt …

Terahertz spectroscopy has been used for almost two decades for investigations of
nanomaterials, including nanocrystals, nanoparticles, nanowires, nanotubes or 2D crystals …

In this review, we discuss the rich ultrafast response at terahertz (THz) frequencies of two-
dimensional (2D) materials. Thanks to their unique optoelectronic properties and …

Conductive thin films are an essential component of many electronic devices. Measuring
their conductivity accurately is necessary for quality control and process monitoring. We …

Electronic applications of large-area graphene films require rapid and accurate methods to
map their electrical properties. Here we present the first electrical resistance tomography …

Graphene metrology needs to keep up with the fast pace of developments in graphene
growth and transfer. Terahertz time-domain spectroscopy (THz-TDS) is a non-contact, fast …

We identify a transient enhancement of the depolarizing field, leading to an unexpected
quench of net polarization, during the growth of a prototypical metal-ferroelectric-metal …

Terahertz (THz) solid immersion microscopy is a modality of THz imaging, which allows one
to overcome the Abbe diffraction limit and provides high energy efficiency due to the …

Despite its great potential for a wide variety of devices, especially mid-infrared biosensors
and photodetectors, graphene plasmonics is still confined to academic research. A major …

We demonstrate that the conductivity of graphene on thin-film polymer substrates can be
accurately determined by reflection-mode air-plasma-based THz time-domain spectroscopy …
