Charge-carrier complexes in monolayer semiconductors
E. Mostaani, R. J. Hunt, D. M. Thomas +6
The photoluminescence (PL) spectra of monolayer (1L) semiconductors feature peaks ascribed to different charge-carrier complexes. We perform diffusion quantum Monte Carlo simulatio…
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.…
Quantum Monte Carlo calculations of energy gaps from first principles
Ryan J. Hunt, Marcin Szyniszewski, Genki I. Prayogo +2
We review the use of continuum quantum Monte Carlo (QMC) methods for the calculation of energy gaps from first principles, and present a broad set of excited-state calculations car…
Localized interlayer complexes in heterobilayer transition metal dichalcogenides
Mark Danovich, David A. Ruiz-Tijerina, Ryan J. Hunt +3
We present theoretical results for the radiative rates and doping-dependent photoluminescence spectrum of interlayer excitonic complexes localized by donor impurities in MoSe/W…
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…
