Accurate Computation of Excitons in Two-Dimensional Semiconducting Transition Metal Dichalcogenides
Abstract
This report presents research conducted by Madeleine Phillips under a Karles Fellowship over the period January 2021 through January 2022. The optoelectronic response of two-dimensional semiconducting transition metal dichalcogenides (TMDs) is dominated by excitons, which are bound states of electrons and holes. The excitonic spectrum of 2D TMDs can be manipulated by stacking TMDs or by stacking and introducing an interlayer twist. This report focuses on the variation of excitonic properties in WSe2 bilayers with two distinct twist angles: 0 and 60 degrees. These bilayers are often referred to as having 3R and 2H stacking, respectively. This work was published in part in the journal Nanoscale in January 2022.
