Ultralow-Tensile Strain Enables Exciton Funneling and Energy Transfer to Boost MoSe2 Photoluminescence Quantum Yield
Gayatri, Mehdi Arfaoui, Debashish Das +14
Strain engineering is a powerful route for controlling the exciton dynamics in van der Waals (vdW) heterostructures (HSs). The interlayer energy transfer (ET) process is another ke…
Geometry-Controlled Magnetic and Electronic Landscapes in Anisotropic van der Waals Materials
Maciej Śmiertka, Ewelina Cybula, Oliwia Janikowska +10
Electronic structure in van der Waals materials is commonly engineered through composition, strain, electrostatic gating and heterostructure assembly. Here we introduce geometronic…
Tunable Magneto-Excitonic Coupling in Alloyed van der Waals Antiferromagnet
Maciej Smiertka, Oliwia Janikowska, Katarzyna Olkowska-Pucko +18
The unique coupling between magnetic order and photo-generated excitons, electron-hole pairs bound by Coulomb interaction, in layered magnetic semiconductors offers a powerful mech…
Magneto-Excitonic Duality From Monolayer to Trilayer CrSBr
Igor Antoniazzi, Łucja Kipczak, Bruno Camargo +7
Two-dimensional (2D) layered magnetic materials (LMMs) are a newly emerging class of van der Waals materials, opening new opportunities to study magneto-excitonic coupling. The air…
Fast Interlayer Energy Transfer from the Lower Bandgap MoS2 to the Higher Bandgap WS2
Gayatri, Mehdi Arfaoui, Debashish Das +9
Energy transfer (ET) is a dipole-dipole interaction, mediated by the virtual photon. Traditionally, ET happens from the higher (donor) to lower bandgap (acceptor) material. However…
Twisted MoSe2 Homobilayer Behaving as a Heterobilayer
Arka Karmakar, Abdullah Al-Mahboob, Natalia Zawadzka +11
Heterostructures (HSs) formed by the transition-metal dichalcogenides (TMDCs) materials have shown great promise in next-generation optoelectronic and photonic applications. An art…
Pressure-induced optical anisotropy of HfS
Igor Antoniazzi, Tomasz Woźniak, Amit Pawbake +8
The effect of pressure on Raman scattering (RS) in the bulk HfS is investigated under hydrostatic and non-hydrostatic conditions. The RS lineshape does not change significantly…
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…
Multidimensional sensing of proximity magnetic fields via intrinsic activation of dark excitons in WSe/CrCl heterostructure
Łucja Kipczak, Zhaolong Chen, Pengru Huang +6
Quantum phenomena at interfaces create functionalities at the level of materials. Ferromagnetism in van der Waals systems with diverse arrangements of spins opened a pathway for ut…
