Hydrogen on silicene: like or unlike graphene?

Michele Pizzochero

Hydrogenation of free-standing silicene, the two-dimensional allotrope of silicon, is investigated in detail using first-principles methods and compared with the adsorption of H atoms on graphene. Similarly to graphene, chemisorption of a single H atom on ...

The Electronic Thermal Conductivity of Graphene

Nicola Marzari

Graphene, as a semimetal with the largest known thermal conductivity, is an ideal system to study the interplay between electronic and lattice contributions to thermal transport. While the total electrical and thermal conductivity have been extensively inv ...

Ising pairing in superconducting NbSe2 atomic layers

László Forró, Helmuth Berger

The properties of two-dimensional transition metal dichalcogenides arising from strong spin-orbit interactions and valley-dependent Berry curvature effects have recently attracted considerable interest(1-7). Although single-particle and excitonic phenomena ...

Selective Functionalization of Graphene Peripheries by using Bipolar Electrochemistry

Klaus Kern, Kannan Balasubramanian

We present a contactless strategy based on bipolar electrochemistry for the local chemical modification of monolayer graphene sheets supported on a substrate. Specifically, peripheral graphene regions are directly modified by copper nanoparticles, the char ...

Unconventional dc Transport in Rashba Electron Gases

Claudio Grimaldi

We discuss the transport properties of a disordered two-dimensional electron gas with strong Rashba spin-orbit coupling. We show that in the high-density regime where the Fermi energy overcomes the energy associated with spin-orbit coupling, dc transport i ...

Rippling ultrafast dynamics of suspended 2D monolayers, graphene

Nicola Marzari, Giovanni Maria Vanacore, Andrea Cepellotti

Here, using ultrafast electron crystallography (UEC), we report the observation of rippling dynamics in suspended monolayer graphene, the prototypical and most-studied 2D material. The high scattering cross-section for electron/matter interaction, the atom ...

A robust molecular probe for Ångstrom-scale analytics in liquids

Andras Kis, Dumitru Dumcenco, Heike Riel, Christos Dimitrakopoulos

Traditionally, nanomaterial profiling using a single-molecule-terminated scanning probe is performed at the vacuum-solid interface often at a few Kelvin, but is not a notion immediately associated with liquid-solid interface at room temperature. Here, usin ...

Observation of Dirac surface states in the noncentrosymmetric superconductor BiPd

Klaus Kern, Christian Reinhard Ast, Peter Wahl

Materials with strong spin-orbit coupling (SOC) have in recent years become a subject of intense research due to their potential applications in spintronics and quantum information technology. In particular, in systems which break inversion symmetry, SOC f ...

A primary battery-on-a-chip using monolayer graphene

Klaus Kern, Kannan Balasubramanian

We present here a bottom-up approach for realizing on-chip on-demand batteries starting out with chemical vapor deposition-grown graphene. Single graphene monolayers contacted by electrode lines on a silicon chip serve as electrodes. The anode and cathode ...
