Fast and Sensitive Terahertz Detection Using an Antenna-Integrated Graphene pn Junction
Sebastián Castilla, Bernat Terrés, Marta Autore +11
Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of se…
Optoelectronic devices, plasmonics and photonics with topological insulators
Antonio Politano, Leonardo Viti, Miriam S. Vitiello
Topological insulators are innovative materials with semiconducting bulk together with surface states forming a Dirac cone, which ensure metallic conduction in the surface plane. T…
Phase-sensitive terahertz imaging using room-temperature near-field nanodetectors
Maria C. Giordano, Leonardo Viti, Oleg Mitrofanov +1
Imaging applications in the terahertz (THz) frequency range are severely restricted by diffraction. Near-field scanning probe microscopy is commonly employed to enable mapping of t…
Black phosphorus nanodevices at terahertz frequencies: photodetectors and future challenges
Leonardo Viti, Antonio Politano, Miriam Serena Vitiello
The discovery of graphene triggered a rapid rise of unexplored two-dimensional materials and heterostructures having optoelectronic and photonics properties that can be tailored on…
Near-field terahertz probes with room-temperature nanodetectors for subwavelength resolution imaging
Oleg Mitrofanov, Leonardo Viti, Enrico Dardanis +5
Near-field imaging with terahertz (THz) waves is emerging as a powerful technique for fundamental research in photonics and across physical and life sciences. Spatial resolution be…
Thermoelectric terahertz photodetectors based on selenium-doped black phosphorus flakes
Leonardo Viti, Antonio Politano, Kai Zhang +1
Chemical doping of bulk black phosphorus is a well-recognized way to reduce surface oxidation and degradation. Here, we report on the fabrication of terahertz frequency detectors c…
