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…
Emergence of New Materials for Exploiting Highly Efficient Carrier Multiplication in Photovoltaics
Sourav Maiti, Marco van der Laan, Deepika Poonia +3
In conventional solar cell semiconductor materials (predominantly Si) photons with energy higher than the band gap initially generate hot electrons and holes, which subsequently co…
