Localized inter-valley defect excitons as single-photon emitters in WSe
L. Linhart, M. Paur, V. Smejkal +3
Single-photon emitters play a key role in present and emerging quantum technologies. Several recent measurements have established monolayer WSe as a promising candidate for a r…
Thermal light emission from monolayer MoS2
Lukas Dobusch, Simone Schuler, Vasili Perebeinos +1
Because of their strong excitonic photoluminescence (PL) and electroluminescence (EL), together with an excellent electronic tunability, transition metal dichalcogenide (TMD) semic…
Optical imaging of strain in two-dimensional crystals
Lukas Mennel, Marco M. Furchi, Stefan Wachter +3
Strain engineering is widely used in material science to tune the (opto-)electronic properties of materials and enhance the performance of devices. Two-dimensional atomic crystals…
Exciton physics and device application of two-dimensional transition metal dichalcogenide semiconductors
Thomas Mueller, Ermin Malic
Two-dimensional group-VI transition metal dichalcogenide semiconductors, such as MoS2, WSe2 and others, exhibit strong light-matter coupling and possess direct band gaps in the inf…
Electroluminescence from multi-particle exciton complexes in transition metal dichalcogenide semiconductors
Matthias Paur, Aday J. Molina-Mendoza, Rudolf Bratschitsch +3
Light emission from higher-order correlated excitonic states has been recently reported in hBN-encapsulated monolayer WSe2 and WS2 upon optical excitation. These exciton complexes…
Atomically thin p-n junctions based on two-dimensional materials
Riccardo Frisenda, Aday J Molina-Mendoza, Thomas Mueller +2
Recent research in two-dimensional (2D) materials has boosted a renovated interest in the p-n junction, one of the oldest electrical components which can be used in electronics and…
