Observation of highly anisotropic bulk dispersion and spin-polarized topological surface states in CoTe2
Atasi Chakraborty, Jun Fujii, Chia-Nung Kuo +4
We present CoTe2 as a new type-II Dirac semimetal supporting Lorentz symmetry violating Dirac fermions in the vicinity of the Fermi energy. By combining first principle ab-initio c…
Collective plasmonic modes in the chiral multifold fermionic material CoSi
Debasis Dutta, Barun Ghosh, Bahadur Singh +4
Plasmonics in topological semimetals offers exciting opportunities for fundamental physics exploration as well as for technological applications. Here, we investigate plasmons in t…
Photonic Topological Transitions and Epsilon-Near-Zero Surface Plasmons in Type-II Dirac Semimetal NiTe
Carlo Rizza, Debasis Dutta, Barun Ghosh +8
Compared to artificial metamaterials, where nano-fabrication complexities and finite-size inclusions can hamper the desired electromagnetic response, several natural materials like…
Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe
Krishna Pandey, Debashis Mondal, John William Villanova +14
The ZrSiS family of compounds hosts various exotic quantum phenomena due to the presence of both topological nonsymmorphic Dirac fermions and nodal-line fermions. In this material…
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…
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…
Spectroscopic investigations of phonons in epitaxial graphene
Antonio Politano
The interaction of graphene with metallic substrates reveals phenomena and properties of great relevance for applications in nanotechnology. In this review, the vibrational charact…
