Polaron spectroscopy of a bilayer excitonic insulator
Ivan Amelio, Neil Drummond, Eugene Demler +2
Recent advances in fabrication of two dimensional materials and their moiré heterostructures have opened up new avenues for realization of ground-state excitonic insulators, where…
Out-of-plane dielectric susceptibility of graphene in twistronic and Bernal bilayers
Sergey Slizovskiy, Aitor Garcia-Ruiz, Alexey I. Berdyugin +6
We describe how the out-of-plane dielectric polarizability of monolayer graphene influences the electrostatics of bilayer graphene -- both Bernal (BLG) and twisted (tBLG). We compa…
Tuning of impurity-bound interlayer complexes in a van der Waals heterobilayer
Fabien Vialla, Mark Danovich, David A. Ruiz-Tijerina +10
Due to their unique two-dimensional nature, charge carriers in semiconducting transition metal dichalcogenides (TMDs) exhibit strong unscreened Coulomb interactions and sensitivity…
Binding energies of excitonic complexes in type-II quantum rings from diffusion quantum Monte Carlo calculations
David Thomas, Ryan Hunt, Neil Drummond +1
Excitonic complexes in type-II quantum-ring heterostructures may be considered as artificial atoms due to the confinement of only one charge-carrier type in an artificial nucleus.…
Diffusion quantum Monte Carlo study of excitonic complexes in two-dimensional transition-metal dichalcogenides
E. Mostaani, M. Szyniszewski, C. H. Price +5
Excitonic effects play a particularly important role in the optoelectronic behavior of two-dimensional semiconductors. To facilitate the interpretation of experimental photoabsorpt…
Binding energies of trions and biexcitons in two-dimensional semiconductors from diffusion quantum Monte Carlo calculations
M. Szyniszewski, E. Mostaani, N. D. Drummond +1
Excitonic effects play a particularly important role in the optoelectronic behavior of two-dimensional (2D) semiconductors. To facilitate the interpretation of experimental photoab…
