  The discovery of graphene and its fascinating capabilities have triggered an
unprecedented interest in inorganic two-dimensional (2D) materials. Van der
Waals (vdW) layered materials as graphene, hexagonal boron nitride (hBN),
transition metal dichalcogenides (TMDs), and the more recently re-discovered
black phosphorus (BP) indeed display an exceptional technological potential for
engineering nano-electronic and nano-photonic devices and components by design,
offering a unique platform for developing new devices with a variety of ad-hoc
properties. In this perspective article, we provide a vision on the key
transformative applications of 2D nanomaterials for the developments of
nanoelectronic, nanophotonic, optical and plasmonic devices, at terahertz
frequencies, highlighting how the rich physical phenomena enabled by their
unique band-structure engineering can allow those devices to boost the vibrant
field of quantum science and quantum technologies.
