Open AccessHigh-throughput computational stacking reveals emergent properties in natural van der Waals bilayers
Stacking of two-dimensional (2D) materials has emerged as a facile strategy for realising exotic quantum states of matter and engineering electronic properties. Yet, developments beyond the proof-of-principle ...

Open AccessCombining density functional theory with macroscopic QED for quantum light-matter interactions in 2D materials
A quantitative and predictive theory of quantum light-matter interactions in ultra thin materials involves several fundamental challenges. Any realistic model must simultaneously account for the ultra-confined...

Open AccessA library of ab initio Raman spectra for automated identification of 2D materials
Raman spectroscopy is frequently used to identify composition, structure and layer thickness of 2D materials. Here, we describe an efficient first-principles workflow for calculating resonant first-order Raman...

Open AccessDissociation of two-dimensional excitons in monolayer WSe2
Two-dimensional (2D) semiconducting materials are promising building blocks for optoelectronic applications, many of which require efficient dissociation of excitons into free electrons and holes. However, the...

Open AccessBand structure engineered layered metals for low-loss plasmonics
Plasmonics currently faces the problem of seemingly inevitable optical losses occurring in the metallic components that challenges the implementation of essentially any application. In this work, we show that ...

Open AccessPlasmonic eigenmodes in individual and bow-tie graphene nanotriangles
In classical electrodynamics, nanostructured graphene is commonly modeled by the computationally demanding problem of a three-dimensional conducting film of atomic-scale thickness. Here, we propose an efficien...
