Tunable surface plasmons in Weyl semimetals TaAs and NbAs
Gennaro Chiarello, Johannes Hofmann, Zhilin Li +5
By means of high-resolution electron energy loss spectroscopy, we investigate the low-energy excitation spectrum of transition-metal monopnictides hosting Weyl fermions. We observe…
Broadband excitation spectrum of bulk crystals and thin layers of PtTe
Barun Ghosh, Francesca Alessandro, Marilena Zappia +8
We explore the broadband excitation spectrum of bulk PtTe using electron energy loss spectroscopy and density functional theory. In addition to infrared modes related to intrab…
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…
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…
