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…
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…
Observation of the quantized motion of excitons in CdSe nanoplatelets
Michele Failla, Francisco García Flórez, Bastiaan B. V. Salzmann +3
We show that the finite lateral sizes of ultrathin CdSe nanoplatelets strongly affect both their photoluminescence and optical absorption spectra. This is in contrast to the situat…
Photoexcitation of PbS Nanosheets Leads to Highly Mobile Charge Carriers and Stable Excitons
Jannika Lauth, Michele Failla, Eugen Klein +3
Solution-processable two-dimensional (2D) semiconductors with chemically tunable thickness and associated tunable band gaps are highly promising materials for ultrathin optoelectro…
Landau polaritons in highly non-parabolic 2D gases in the ultra-strong coupling regime
Janine Keller, Giacomo Scalari, Felice Appugliese +11
We probe ultra-strong light matter coupling between metallic terahertz metasurfaces and Landau-level transitions in high mobility 2D electron and hole gases. We utilize heavy-hole…
