Temperature Dependence of Phonon Energies and Lifetimes in Single- and Few-layered Graphene
Markos Poulos, Konstantinos Papagelis, Emmenuel N. Koukaras +3
In this work, we have studied the phonon properties of multi-layered graphene with the use of Molecular Dynamics (MD) simulations and the k-space Autocorrelation Sequence (k-VACS)…
Occurrence of the collective Ziman limit of heat transport in cubic semiconductors: scattering channels and size effects
Jelena Sjakste, Maxime Markov, Raja Sen +2
In this work, we discuss the possibility of reaching the Ziman conditions for collective heat transport in cubic bulk semiconductors, such as Si, Ge, AlAs and AlP. In natural and e…
Hydrodynamic heat transport regime in bismuth: a theoretical viewpoint
Maxime Markov, Jelena Sjakste, Giuliana Barbarino +5
Bismuth is one of the rare materials in which second sound has been experimentally observed. Our exact calculations of thermal transport with the Boltzmann equation predict the occ…
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-…
Excitons in van der Waals materials: from monolayer to bulk hexagonal boron nitride
Jaakko Koskelo, Giorgia Fugallo, Mikko Hakala +3
We present a general picture of the exciton properties of layered materials in terms of the excitations of their single-layer building blocks. To this end, we derive a model excito…
Exciton energy-momentum map of hexagonal boron nitride
Giorgia Fugallo, Matteo Aramini, Jaakko Koskelo +6
Understanding and controlling the way excitons propagate in solids is a key for tailoring materials with improved optoelectronic properties. A fundamental step in this direction is…
