Optical properties of orthorhombic germanium sulfide: Unveiling the Anisotropic Nature of Wannier Exciton
Mehdi Arfaoui, Natalia Zawadzka, Sabrine Ayari +7
To fully explore exciton-based applications and improve their performance, it is essential to understand the exciton behavior in anisotropic materials. Here, we investigate the opt…
Manipulating single photon emitter radiative lifetime in transition-metal dichalcogenides through Forster resonance energy transfer to graphene
R. Eddhib, S. Ayari, A. Hichri +1
Structural defects can crucially impact the optical response of monolayer (ML) thick materials as they enable trapping sites for excitons. These trapped excitons appear in photolum…
Phonon-assisted exciton and trion conversion efficiency in transition metal Dichalcogenides
Sabrine Ayari, Sihem Jaziri, Robson Ferreira +1
Photoluminescence spectra, shows that monolayer Transition-metal dichalcogenides (MLTMDCs), possess charged exciton binding energies, conspicuously similar to the energy of optical…
Radiative lifetime of localized excitons in transition metal dichalcogenides
Sabrine Ayari, Adlen Smiri, Aida Hichri +2
Disorder derived from defects or strain in monolayer TMDs can lead to a dramatic change in the physical behavior of the interband excitations, producing inhomogeneous spectral broa…
Exciton, trion and localized exciton in monolayer Tungsten Disulfide
Aïda Hichri, Imen Ben Amara, Sabrine Ayari +1
The ultrathin transition metal dichalcogenides (TMDs) have emerged as promising materials for various applications using two dimensional (2D) semiconductors. They have attracted in…
