Abstract

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.
