  • This makes the results of the discussed paper incorrect.

Abstract

A comment about the paper “Tunneling effect on second-harmonic generation in quantum dot molecule, Superlattices and Microstructures 91 (2016) 358–364” is provided. It is shown that the formula used by the authors for the study of the second-harmonic generation coefficient cannot apply in the system under study. Therefore, the results of the paper are incorrect.

    This consists of two SQDs with different band structures, which are coupled by tunneling and the tunneling coefficient is controlled by an external voltage. This nanostructure has led to several interesting phenomena, including tunneling induced transparency, Autler-Townes splitting and emergence of slow light [42,43], creation of robust states and controlled indirect exciton population transfer [44–46], tunneling modified time-dependent absorption and alteration between absorption and gain [47], enhanced pump-probe optical response and four-wave mixing [48,49] and others [50–54]. Interestingly, the optical properties of hybrid structures composed of an asymmetric double SQD molecule and a MNP remain relatively unexplored.
