 oiré materials - Imperial College London

DESCRIPTION:Excitons play a key role for the optical properties of 2D semi
 conductors\, but it can be difficult to understand the results of experime
 ntal measurements. To address this challenge\, theoretical calculations of
  excitonic properties provide useful insights. However\, performing such c
 alculations for systems containing defects or moiré patterns can be compu
 tationally challenging. In my talk I will present results for optical prop
 erties of charged defects in 2D semiconductors and also for twisted bilaye
 rs of 2D semiconductors obtained from an efficient implementation of the B
 ethe-Salpeter equation based on accurate tight-binding models.
