Magnetism, symmetry and spin transport in van der Waals layered systems
Hidekazu Kurebayashi, Jose H. Garcia, Safe Khan +2
The discovery of an ever increasing family of atomic layered magnetic materials, together with the already established vast catalogue of strong spin-orbit coupling (SOC) and topolo…
Thermal Transport in Amorphous Graphene with Varying Structural Quality
Aleandro Antidormi, Luciano Colombo, Stephan Roche
The synthesis of wafer-scale two-dimensional amorphous carbon monolayers has been recently demonstrated. This material presents useful properties when integrated as coating of meta…
Exploring Phononic Properties of Two-Dimensional Materials using Machine Learning Interatomic Potentials
Bohayra Mortazavi, Ivan S. Novikov, Evgeny V. Podryabinkin +4
Phononic properties are commonly studied by calculating force constants using the density functional theory (DFT) simulations. Although DFT simulations offer accurate estimations o…
Scaling Properties of Polycrystalline Graphene: A Review
Andreas Isacsson, Aron W. Cummings, Luciano Colombo +3
