Microscopic screening theory for excitons in two-dimensional materials: A bridge between effective models and ab initio descriptions
P. Ninhos, A. J. UrÃa-Ãlvarez, A. J. Uría-Álvarez +3
We present a computational approach for exciton calculations in two-dimensional (2D) materials within the Bethe-Salpeter equation (BSE) framework, employing an atomistic descriptio…

Understanding Memristive Behavior: An Atomistic Study of the Influence of Grain Boundaries on Surface and Out-of-Plane Diffusion of Metallic Atoms
Mohit D. Ganeriwala, Daniel Luque-Jarava, Francisco Pasadas +4
Atomic migration from metallic contacts, and subsequent filament formation, is recognised as a prevailing mechanism leading to resistive switching in memristors based on two-dimens…
