Anisotropic dependence of radiation from excitons in Ga₂O₃/MoS₂ heterostructure.

ABSTRACT: The anisotropic dependence of radiation arising from exciton recombination in the Ga₂O₃/MoS₂ heterostructure is investigated, using density functional theory and the Bethe-Salpeter equation. The wurtzite (WZ) and zinc blende (ZB) structures of the Ga₂O₃ monolayer with ferroelectric (FE) properties are assembled with a MoS₂ monolayer. Projected band structure, charge transfer and life time of excitons are discussed, to analyze which transition may be important to the creation of excitons from the electron-hole pair. A general formula of the angle-dependent intensities of radiation is derived. The characteristics of angle-dependent intensities that are closely related to the dipole moment of excitons are discussed, from the vi
