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…
Metallic-Phase-FeGaTe Enabled Interface Engineering for Self-Powered and High-Gain WS Photodetectors
Wajid Ali, Ming Huang, Juan Li +7
Two-dimensional transition-metal dichalcogenides offer strong light-matter interaction but suffer from inefficient carrier separation and contact-related losses in photodetectors.…
Dopant-induced modifications of the optical properties of GaSe
Jakub Sójka, Katarzyna Olkowska-Pucko, Kacper Walczyk +5
Doping plays a crucial role in tailoring the electronic, optical, and magnetic properties of semiconductors, enabling control of carrier dynamics and the formation of functional st…
Resonant Raman scattering in bilayer 3R-MoS
Chinmay K. Mohanty, Kacper Walczyk, Tomasz Woźniak +5
Raman scattering is a powerful spectroscopic technique widely employed to investigate light-matter interactions and lattice dynamics in two-dimensional materials. Here, we investig…
Doping-Induced Brightening of Dark Excitons and Trions in a WSe Monolayer
Grzegorz Krasucki, Artur O. Slobodeniuk, Kacper Walczyk +5
Optically dark excitonic states play a critical role in the valleytronic, electronic, and optical properties of monolayer semiconducting transition metal dichalcogenides. Here, we…
Strong Spin-Lattice Interaction in Layered Antiferromagnetic CrCl
Łucja Kipczak, Tomasz Woźniak, Chinmay K. Mohanty +10
Understanding the coupling between lattice vibrations and magnetic order is crucial for controlling properties of two-dimensional magnetic materials. Here, we investigate the vibra…
