Tuning electronic properties in transition metal dichalcogenides MX (M= Mo/W, X= S/Se) heterobilayers with strain and twist angle
Ravina Beniwal, M. Suman Kalyan, Nicolas Leconte +3
We explore the direct to indirect band gap transitions in MX (M= Mo/W, X= S/Se) transition metal dichalcogenides heterobilayers for different system compositions, strains, and…

Directly visualizing the momentum forbidden dark excitons and their dynamics in atomically thin semiconductors
Julien Madéo, Michael K. L. Man, Chakradhar Sahoo +11
Resolving the momentum degree of freedom of excitons - electron-hole pairs bound by the Coulomb attraction in a photoexcited semiconductor, has remained a largely elusive goal for…
