The role of surface chemical reactivity in the stability of electronic nanodevices based on two-dimensional materials "beyond graphene" and topological insulators
A. Politano, M. S. Vitiello, L. Viti +2
Here, we examine the influence of surface chemical reactivity toward ambient gases on the performance of nanodevices based on two-dimensional materials "beyond graphene" and novel…
Plasmonics with two-dimensional semiconductors "beyond graphene": from basic research to technological applications
Amit Agarwal, Miriam S. Vitiello, Leonardo Viti +2
In this minireview, we explore the main features and the prospect of plasmonics with two-dimensional semiconductors. Plasmonic modes in each class of van der Waals semiconductors h…
Terahertz detection of magnetic field-driven topological phase transition in HgTe-based transistors
A. Kadykov, F. Teppe, C. Consejo +12
We report on Terahertz detection by inverted band structure HgTe-based Field Effect Transistor up to room temperature. At low temperature, we show that nonlinearities of the transi…

Probing topological insulators surface states via plasma-wave Terahertz detection
Leonardo Viti, Dominique Coquillat, Antonio Politano +7
Topological insulators (TIs) represent a novel quantum state of matter, characterized by edge or surface-states, showing up on the topological character of the bulk wave functions.…
Unusually strong lateral interaction in the CO overlayer in phosphorene-based systems
Antonio Politano, Miriam Serena Vitiello, Leonardo Viti +5
By means of vibrational spectroscopy and density functional theory (DFT), we investigate CO adsorption on phosphorene-based systems. We find stable CO adsorption at room temperatur…
