Low-energy type-II Dirac fermions and spin-polarized topological surface states in transition-metal dichalcogenide NiTe
Barun Ghosh, Debashis Mondal, Chia-Nung Kuo +6
Using spin- and angle- resolved photoemission spectroscopy (spin-ARPES) together with calculations, we demonstrate the existence of a type-II Dirac semimetal stat…
A novel undamped gapless plasmon mode in tilted type-II Dirac semimetal
Krishanu Sadhukhan, Antonio Politano, Amit Agarwal
We predict the existence of a novel long-lived gapless plasmon mode in a type-II Dirac semimetal (DSM). This gapless mode arises from the out-of-phase oscillations of the density f…
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…
Liquid-phase exfoliated indium-selenide flakes and their application in hydrogen evolution reaction
Elisa Petroni, Emanuele Lago, Sebastiano Bellani +12
Single- and few-layered InSe flakes are produced by the liquid-phase exfoliation of beta-InSe single crystals in 2-propanol, obtaining stable dispersions with a concentration as hi…
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…
