Comment on the paper 'Third-harmonic generation investigated by a short-range bottomless exponential potential well' by M. Hu, K. Guo, Q. Yu, Z. Zhang [Superlattices and Microstructures, 122 (2018) 538-547]

摘要

We have discovered several severe errors in the recent paper M. Hu, K. Guo, Q. Yu, Z. Zhang [Superlattices and Microstructures, 122 (2018) 538-547]. Specifically, we demonstrate that both the solution of the Schrodinger equation and the bound-state wave functions used in the paper are incorrect. In the recent paper [1], the authors discuss the third-harmonic generation investigated by a short-range bottomless exponential potential well. Unfortunately, the paper contains several severe mistakes.
