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…
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…
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…
Moiré-localized interlayer exciton wavefunctions captured by imaging its electron and hole constituents
Ouri Karni, Elyse Barré, Vivek Pareek +21
Interlayer excitons (ILXs) - electron-hole pairs bound across two atomically thin layered semiconductors - have emerged as attractive platforms to study exciton condensation, singl…
Experimental measurement of the intrinsic excitonic wavefunction
Michael K. L. Man, Julien Madéo, Chakradhar Sahoo +15
An exciton, a two-body composite quasiparticle formed of an electron and hole, is a fundamental optical excitation in condensed-matter systems. Since its discovery nearly a century…
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…
