Bulk and Surface Electronic Structure of the Dual-Topology Semimetal Pt2HgSe3

Nicola Marzari, Marco Gibertini, Antimo Marrazzo

We report high-resolution angle-resolved photoemission measurements on single crystals of Pt2HgSe3 grown by high-pressure synthesis. Our data reveal a gapped Dirac nodal line whose (001) projection separates the surface Brillouin zone in topological and tr ...

Emergent dual topology in the three-dimensional Kane-Mele Pt2HgSe3

Nicola Marzari, Marco Gibertini, Antimo Marrazzo

Recently, the very first large-gap Kane-Mele quantum spin Hall insulator was predicted to be monolayer jacutingaite (Pt2HgSe3), a naturally occurring exfoliable mineral discovered in Brazil in 2008. The stacking of quantum spin Hall monolayers into a van-d ...

Multi-frequency Shubnikov-de Haas oscillations in topological semimetal Pt2HgSe3

Marco Gibertini

Monolayer jacutingaite (Pt2HgSe3) has been recently identified as a candidate quantum spin Hall system with a 0.5 eV band gap, but no transport measurements have been performed so far on this material, neither in monolayer nor in the bulk. By using a dedic ...

Probing magnetism in 2D materials at the nanoscale with single-spin microscopy

Marco Gibertini, Zheng Wang

The discovery of ferromagnetism in two-dimensional (2D) van der Waals (vdW) crystals has generated widespread interest. Making further progress in this area requires quantitative knowledge of the magnetic properties of vdW magnets at the nanoscale. We used ...

Enhanced Electron-Phonon Interaction in Multivalley Materials

Nicola Marzari, Marco Gibertini, Helmuth Berger, Thibault Daniel Pierre Sohier, Evgeniy Ponomarev

We report a combined experimental and theoretical investigation that reveals a new mechanism responsible for the enhancement of electron-phonon coupling in doped semiconductors in which multiple inequivalent valleys are simultaneously populated. Using Rama ...

Valley-Engineering Mobilities in Two-Dimensional Materials

Nicola Marzari, Giovanni Pizzi, Marco Gibertini, Davide Campi, Thibault Daniel Pierre Sohier

Two-dimensional materials are emerging as a promising platform for ultrathin channels in field-effect transistors. To this aim, novel high-mobility semiconductors need to be found or engineered. Although extrinsic mechanisms can in general be minimized by ...

Determining the phase diagram of atomically thin layered antiferromagnet CrCl3

Marco Gibertini, Dumitru Dumcenco, Zhe Wang

Changes in the spin configuration of atomically thin, magnetic van der Waals multilayers can cause drastic modifications in their opto-electronic properties. Conversely, the opto-electronic response of these systems provides information about the magnetic ...

Magnetic 2D materials and heterostructures

Marco Gibertini

The family of two-dimensional (2D) materials grows day by day, hugely expanding the scope of possible phenomena to be explored in two dimensions, as well as the possible van der Waals (vdW) heterostructures that one can create. Such 2D materials currently ...

Relative Abundance of Z(2) Topological Order in Exfoliable Two-Dimensional Insulators

Nicola Marzari, Marco Gibertini, Nicolas Frank Mounet, Antimo Marrazzo, Davide Campi

Quantum spin Hall insulators make up a class of two-dimensional materials with a finite electronic band gap in the bulk and gapless helical edge states. In the presence of time-reversal symmetry, Z(2) topological order distinguishes the topological phase f ...
