The optical absorption in indirect semiconductor to semimetal PtSe2 arises from direct transitions
Marin Tharrault, Sabrine Ayari, Mehdi Arfaoui +12
is a van der Waals material transitioning from an indirect bandgap semiconductor to a semimetal with increasing thickness. Its absorption threshold has been conjectur…
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…
Atomic Layer-controlled Nonlinear Terahertz Valleytronics in Dirac Semi-metal and Semiconductor PtSe2
Minoosh Hemmat, Sabrine Ayari, Martin Micica +16
Platinum diselenide (PtSe2) is a promising two-dimensional (2D) material for the terahertz (THz) range as, unlike other transition metal dichalcogenides (TMDs), its bandgap can be…
Hyperfine Interaction in a MoS Quantum Dot: Decoherence of a Spin-Valley Qubit
Mehdi Arfaoui, Sihem Jaziri
A successful and promising device for the physical implementation of electron spin-valley based qubits is the Transition Metal Dichalcogenide monolayer (TMD-ML) semiconductor quant…
Quantum beats of coherent 1s 2s excitons in two dimensional transition metal
Nizar Chaouachi, Sihem Jaziri
Motivated by recent experimental measurement of the intrinsic excitonic wave-function in 2D Transition-metal dichalcogenides (TMDs) by angle-resolved photoemission spectroscopy (AR…
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…
