Abstract
-with indirect Heyd-Scuseria-Ernzerhof (HSE06) band gaps ranging from 1.24-1.90 eV. Excitonic effects induced by quantum confinement contribute to exciton binding energies from 210-470 meV, consistent with typical 2D materials. Additionally, some monolayers demonstrate potential for solar harvesting applications, with predicted energy conversion efficiency approaching 30% under full photon absorption.
