1 Correction to: Applied Physics A (2018) 124:428 https://doi.org/10.1007/s00339-018-1862-4

Dear readers,


The authors recently found a few mistakes in their published paper.

On page 6 of this paper.

The units of ‘Eb or E’ in Fig. 7b, Table 2 and Line 7 of paragraph 1 should be corrected as ‘V/cm’ instead of ‘kV/cm’.

Combining common sense with the results of Fig. 8b, it is easy to find that the units of ‘Eb or E’ mentioned above are uncorrect.

These errors do not alter the results or discussions. The authors express sincere apologies for any inconvenience caused.

  1. 1.

    The abscissa unit of Fig. 7b should be corrected as E (V/cm) instead of E (kV/cm). Figure 7 is corrected in this corrigendum, as follows:

  2. 2.

    The unit of Eb in Table 2 should be corrected as Eb (V/cm).

    Table 2 is corrected in this corrigendum, as follows:

    On Page 6, Line 7 of paragraph 1, the sentence ‘the minimum α (3.012), Eb (90.2 kV/cm) and nearly the lowest ρ (4 × 104 Ω m)’ should be corrected as ‘the minimum α (3.012), Eb (90.2 V/cm) and nearly the lowest ρ (4 × 104 Ω m)’.
