TL;DR: It is shown that the Coulomb interaction-induced self-energy corrections in real space are sufficiently nonlocal to be manipulated externally, but still local enough to induce spatially sharp interfaces within a single homogeneous monolayer to form heterojunctions.

TL;DR: The main effect of increased external dielectric screening is a reduction of the quasiparticle band gap, with rigid shifts to the bands themselves, in the atomically thin, quasi-two-dimensional semiconductor WS_{2}.

TL;DR: In this paper, the authors investigate how external screening shapes excitons in two-dimensional semiconductors embedded in laterally structured dielectric environments, and they find that the ground-state exciton is least influenced, while higher excitations are attracted towards regions with high dielectoric constant of the environment.

TL;DR: In this article, a spatially resolved spectra unravels the gradual increase of the graphene phonon signatures with progressive delamination of graphene from the metal surface by wrinkles and blisters.

TL;DR: In this article, the potential of monolayer semiconducting transition-metal dichalcogenides (TMDCs) for Coulomb engineering in a material realistic and quantitative manner.
