Author Correction: Discrete interactions between a few interlayer excitons trapped at a MoSe2–WSe2 heterointerface

The forth sentence after Equation (5) originally read “The experimentally observed blueshift of LIX2 of (8.4 ± 0.6) meV is consistent with a confinement lengthscale in the range l= 2.8–3.3 nm”. In the corrected version “l= 2.8–3.3 nm” is replaced by “l= 2.5–3.0 nm”. The eighth sentence after Equation (5) originally read “Remarkably, ... for a dielectric constant in the range ε⪆ 3, ... and an effective confinement lengthscale of l ≈ 3 nm.” In the corrected version “ε⪆ 3” is replaced by “ε ≈ 3” and “l ≈ 3 nm” is replaced by “l⪅ 3 nm”.

The authors became aware of a numeric error in a parameter they used (dipolar interactions) in the model to interpret their experimental findings. As a result of this error, the following changes have been made to the original version of this Article: In "Modelling interactions in multi-exciton complexes" under "Results and discussion", the forth sentence of the first paragraph originally stated "For values of ℓ~3-4 nm, reference to Fig. 3a shows that Δρ~5-6.5 nm." In the corrected version "Δρ5 -6.5 nm" is replaced by "Δρ~4.5-5.5 nm".
The correct version of Fig. 3 is shown below after correcting the dipolar repulsion and exchange splitting energy (~20% differences).
This has now been corrected in both the PDF and HTML versions of the Article. The original Supplementary Equations (4-7) incorrectly read: The correct form of Supplementary Equations (4-7) is: The original Supplementary Equations (8-11) incorrectly read: The correct form of Supplementary Equations (8-11) is: The original Supplementary Equations (12-15) incorrectly read: The correct form of Supplementary Equations (12-15) is: The third sentence after Supplementary Equation (21) originally read "For example, arranging three excitons in a line would result in U 3X 0;line ≈ 3.496Ẽ > U 3X 0 , a quadexciton with three excitons on a triangle and the fourth one in the center would give U 4X 0;triangle ≈ 5.493Ẽ > U 4X 0 and a quintexciton consisting of four excitons on a square surrounding the fifth in the trap center would have U 5X 0;square ≈ 7.845Ẽ > U 5X 0 ." In the corrected version "3.496Ẽ" is replaced by "2.650Ẽ", "5.493Ẽ" is replaced by "4.163Ẽ" and "7.845 E" is replaced by "5.945Ẽ".
The HTML has been updated to include a corrected version of the Supplementary Information.
