This article has been retracted at the request of the Editor. Post-publication, it came to the attention of the journal that the authors did not obtain the necessary approval from the journal editor for the addition of a new author and a change to the author order, which is contrary to the journal policy on changes to authorship. In addition, the newly added author (Dr. C.A. Duque) had been suggested as a reviewer by the authors at the submission stage. The editor reached out to the authors for an explanation to the above points, but they failed to provide a satisfactory explanation. Overall, the editor believes that adding a new author at the revision stage without obtaining the necessary approval from the journal editor is contrary to the journal policies and decided to retract the paper. © 2025 Elsevier B.V.en10.1016/j.physleta.2025.130471info:eu-repo/semantics/closedAccessRetraction notice to “The combined effects of electric field and embedded dielectric matrix on the electronic and optical properties in Ge/SiGe core/shell quantum dots and its SiGe/Ge inverted structure” [Physics Letters A (2024) 129760] (Physics Letters A (2024) 523, (S0375960124004547), (10.1016/j.physleta.2024.129760))Erratum5442-s2.0-105001150262Q2
