Exchange Enhancement of the Electron-Phonon Interaction: the Case of Weakly Doped Two-Dimensional Multivalley Semiconductors
Betul Pamuk, Paolo Zoccante, Jacopo Baima +2
The effect of the exchange interaction on the vibrational properties and on the electron-phonon coupling were investigated in several recent works. In most of the case, exchange te…
Advanced capabilities for materials modelling with Quantum ESPRESSO
P. Giannozzi, O. Andreussi, T. Brumme +47
Quantum ESPRESSO is an integrated suite of open-source computer codes for quantum simulations of materials using state-of-the art electronic-structure techniques, based on density-…
Anharmonic phonon spectra of PbTe and SnTe in the self-consistent harmonic approximation
Guilherme A. Ribeiro, Lorenzo Paulatto, Raffaello Bianco +3
At room temperature, PbTe and SnTe are efficient thermoelectrics with a cubic structure. At low temperature, SnTe undergoes a ferroelectric transition with a critical temperature s…
Flat Electronic Bands in Long Sequences of Rhombohedral-stacked Multilayer Graphene
Hugo Henck, Jose Avila, Zeineb Ben Aziza +15
The crystallographic stacking order in multilayer graphene plays an important role in determining its electronic properties. It has been predicted that a rhombohedral (ABC) stackin…
High- superconductivity in weakly electron-doped HfNCl
Betül Pamuk, Francesco Mauri, Matteo Calandra
We investigate the magnetic and superconducting properties in electron-doped LiHfNCl. HfNCl is a band insulator that undergoes an insulator to superconductor transition upon do…
The Raman fingerprint of rhombohedral graphite
Abderrezak Torche, Francesco Mauri, Jean-Christophe Charlier +1
Multi-layer graphene with rhombohedral stacking is a promising carbon phase possibly displaying correlated states like magnetism or superconductivity due to the occurrence of a fla…
