Excitons in atomically thin transition metal dichalcogenides
Gang Wang, Alexey Chernikov, Mikhail M. Glazov +4
Atomically thin materials such as graphene and monolayer transition metal dichalcogenides (TMDs) exhibit remarkable physical properties resulting from their reduced dimensionality…
Valley Dynamics of Excitons in Monolayer Dichalcogenides
Gerd Plechinger, Philipp Nagler, Ashish Arora +6
Monolayer transition-metal dichalcogenides (TMDCs) have recently emerged as possible candidates for valleytronic applications, as the spin and valley pseudospin are directly couple…
Giant Zeeman splitting inducing near-unity valley polarization in van der Waals heterostructures
Philipp Nagler, Mariana V. Ballottin, Anatolie A. Mitioglu +8
Monolayers of semiconducting transition metal dichalcogenides exhibit intriguing fundamental physics of strongly coupled spin and valley degrees of freedom for charge carriers. Whi…
Interlayer exciton dynamics in a dichalcogenide monolayer heterostructure
Philipp Nagler, Gerd Plechinger, Mariana V. Ballottin +8
In heterostructures consisting of different transition-metal dichalcogenide monolayers, a staggered band alignment can occur, leading to rapid charge separation of optically genera…
Spectral focusing of broadband silver electroluminescence in nanoscopic FRET-LEDs
Robin P. Puchert, Florian Steiner, Gerd Plechinger +10
Few inventions have shaped the world like the incandescent bulb. While Edison used thermal radiation from ohmically heated conductors, some noble metals exhibit "cold" electrolumin…
Coulomb engineering of the bandgap in 2D semiconductors
Archana Raja, Andrey Chaves, Jaeeun Yu +13
The ability to control the size of the electronic bandgap is an integral part of solid-state technology. Atomically-thin two-dimensional crystals offer a new approach for tuning th…
