Correction to: npj 2D Materials and Applications https://doi.org/10.1038/s41699-018-0050-x, published online 8 March 2018

The authors became aware of a mistake in the original version of the paper in which they mistakenly assumed a 2Hb polytype (P \(\bar 6{\mathrm{m2}}\) space group) for the Mo- and W- based TMDs, but these are actually 2Hc polytype (P63/mmc space group) [Phys. Rev. B, 69:134111, (2004)]. As a result of this, the following changes have been made to the original version of this Article:

The fifth sentence of the abstract originally read “Overall, the out-of-plane dielectric constant of the TMDs and h-BN increases by around 15% as the number of layers is increased from monolayer to bulk, while the in-plane component remains unchanged.” In the corrected version, “around 15%” is replaced by “less than 15%”.

The third sentence of the sixth paragraph of the Results and discussion originally stated “Mo-based TMDs show an increase of 15% in the out-of-plane dielectric constant when going from monolayer to bulk while W-based TMDs show an increase of about 5%”. In the corrected version, “show an increase of 15%” is replaced by “show an increase of 13%”.

The last sentence of the seventh paragraph of the “Results and Discussion” originally stated “Indeed, we find that the ionic response in the in-plane direction reduces from 53.7 to 12.30 when we theoretically convert monolayer HfS2 from the 1T to the 2H structure”. In the corrected version, “from 53.7 to 12.30” is replaced by “from 53.7 to 14.70”.

The seventh sentence of the first paragraph of the “Details of the ab initio calculations” section of the Methods originally read “The value of n which results in converged dielectric constants for bulk 2H TMDs and h-BN turned out be 8, whereas, its counterpart for bulk 1T TMDs is 16”. The corrected version reads “The value of n which results in converged dielectric constants for bulk 2H TMDs, h-BN, and 1T TMDs turns out to be 12, 8, and 16, respectively”.

The Data availability originally read “The data that support the findings of this study are available at http://repository.nomad-coe.eu/NomadRepository-1.1/search/index.zul”. The corrected version reads “The data that supports the findings of this study is available at https://doi.org/10.17172/NOMAD/2020.07.17-1”.

In Table 2, most values of out-of-plane (ϵ⊥) and in-plane (ϵ||) dielectric constants of Mo-based and W-based TMDs are updated, as well as ϵ0,⊥ of bilayer HfSe2(T). The correct version of Table 2 appears below:

Table 2 TMDs: in-plane and out-of-plane macroscopic dielectric constant of monolayer, bilayer and bulk.
Full size table

which replaces the previous incorrect version:

Table 2 TMDs: in-plane and out-of-plane macroscopic dielectric constant of monolayer, bilayer and bulk.
Full size table

In Table 3, most values of thicknesses and the in-plane lattice constants of the Mo-based and W-based TMDs are updated. The correct version of Table 3 appears below:

Table 3 Simulation parameters used for the calculation of macroscopic dielectric constants of 2D materials.
Full size table

which replaces the previous incorrect version:

Table 3 Simulation parameters used for the calculation of macroscopic dielectric constants of 2D materials.
Full size table

Figures 2 and 3 depict the static and optical dielectric constants for layered TMDs, respectively, with the same dataset listed in Table 2. The correct version of Fig. 2 is:

figure 1

Fig. 2

replaces the previous incorrect version:

And the correct version of Fig. 3:

figure 2

Fig. 3

replaces the previous incorrect version:

In Fig. 4, the 2H bilayer structure is modified. The correct version of Fig. 4 is:

figure 3

Fig. 4

which replaces the previous incorrect version:

After the sentence “Bilayer h-BN stacked in A-A’ order” in the legend for Fig. 4, the following sentence has been added: “a is the in-plane lattice constant whereas t, the distance between the metal atom planes in the bilayer structure, corresponds to the monolayer thickness”.

These have been corrected in both the PDF and HTML versions of the Article.
