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…
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…
Resonant Raman Scattering of Few Layers CrBr
Łucja Kipczak, Arka Karmakar, Magdalena Grzeszczyk +9
We investigate the vibrational and magnetic properties of thin layers of chromium tribromide (CrBr) with a thickness ranging from three to twenty layers (3~L to 20~L) revealed…
Excitation-Dependent High-Lying Excitonic Exchange via Interlayer Energy Transfer from Lower-to-Higher Bandgap 2D Material
Arka Karmakar, Tomasz Kazimierczuk, Igor Antoniazzi +8
High light absorption (~15%) and strong photoluminescence (PL) emission in monolayer (1L) transition metal dichalcogenide (TMD) make it an ideal candidate for optoelectronic applic…
Dominating Interlayer Resonant Energy Transfer in Type-II 2D Heterostructure
Arka Karmakar, Abdullah Al-Mahboob, Christopher E. Petoukhoff +5
Type-II heterostructures (HSs) are essential components of modern electronic and optoelectronic devices. Earlier studies have found that in type-II transition metal dichalcogenide…
Directly visualizing the momentum forbidden dark excitons and their dynamics in atomically thin semiconductors
Julien Madéo, Michael K. L. Man, Chakradhar Sahoo +11
Resolving the momentum degree of freedom of excitons - electron-hole pairs bound by the Coulomb attraction in a photoexcited semiconductor, has remained a largely elusive goal for…
