Effects of structure and temperature on the nature of excitons in the Mo0.6W0.4S2 alloys
Deepika Poonia, Nisha Singh, Jeff J. P. M. Schulpen +7
We have studied the nature of excitons in the transition metal dichalcogenide alloy Mo0.6W0.4 S2, compared to pure MoS2 and WS2 grown by atomic layer deposition (ALD). For this, op…
Generating Triplets in Organic Semiconductor Tetracene upon Photoexcitation of Transition Metal Dichalcogenide ReS
Sourav Maiti, Deepika Poonia, Pieter Schiettecatte +4
We studied the dynamics of transfer of photoexcited electronic states in a bilayer of the two-dimensional transition metal dichalcogenide ReS and tetracene, with the aim to pro…
Unraveling the Photophysics of Liquid-Phase Exfoliated Two-Dimensional ReS2 Nanoflakes
Pieter Schiettecatte, Deepika Poonia, Ivo Tanghe +6
Few-layered transition metal dichalcogenides (TMDs) are increasingly popular materials for optoelectronics and catalysis. Amongst the various types of TMDs available today, rhenium…
Topological Wannier excitons in bismuth chalcogenide nanosheets I: Single-particle properties
L. Maisel Licerán, F. García Flórez, Laurens D. A. Siebbeles +1
We analyze the topology and dispersion of bulk Wannier excitons in nanosheets of topological insulators in the family of bismuth chalcogenides. Our main finding is that excitons al…
