Concern has been raised about the publication of this article as we found similarities of this paper in the paper: Growth of room-temperature 1.32-μm-emitting InAs quantum dots using {GaAs/InAs} quasi-monolayers, Jong Su Kim, Dong-Youn Lee, I.H. Ban, Gu-Hyun Kim, Se-Kyung Kang, S.I. Ban, J.I. Lee, Jin Soo Kim, Sang-Hoen Lee, Hyun Kwang Choi, Minhyon Jeon, Jae-Young Leem, Journal of the Korean Physical Society, Vol. 42 No. III, [2003] 237–240. https://doi.org/10.3938/jkps.42.237. The simultaneous submission or duplicate publication of a manuscript, and the lack of consistent authorship attribution are considered serious breaches of scientific ethics.
