In traditional electron configurations of atoms, the principal quantum numbers are always positive integers and describe the energy levels of the electrons in an atom. The concept of noninteger (effective) principal quantum numbers, first proposed by Slater, has appeared in some advanced and theoretical contexts, often involving the true total energy of systems or extensions beyond standard approximation models. This phenomenon, the origin of which is still unclear, has recently been solved by explaining that it is due to the fractal structure of atoms and molecules, which is also considered proof that atoms and molecules have a fractal structure. In this paper the new electron configuration of atoms is proposed, the main concept of this configuration is based on the fractal nature of atoms and molecules, in which the general configuration includes noninteger principal quantum numbers is in viewpoint. The paper addresses the electron configuration of atoms according to the fractal structure of atoms, a longstanding problem in quantum physics that remains unsolved despite considerable interest and theoretical progress. It is believed that the proposed new electron configuration method will provide excellent progress in the study of the atomic and molecular structure of natural sciences.</p></div>","PeriodicalId":770,"journal":{"name":"Russian Physics Journal","volume":"68 5","pages":"796 - 803"},"PeriodicalIF":0.4,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144990615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Formation energies of the Cu impurity in the investigated doping sites in m‑ZrO<sub>2</sub> suggest that Cu substitution for Zr (Cu<sub>Zr</sub>) is generally more favorable under oxygen-rich conditions. Substitution of Cu for O becomes significant under oxygen-lean conditions. However, the formation energy obtained for Cu substituting O, is relatively high and positive (1.63 eV) demonstrating the difficulty of formation. Cu substituting for Zr in m‑ZrO<sub>2</sub> with different oxygen vacancy (<i>V</i><sub>O</sub>) positions relative to the Cu impurity is simulated. The structural calculation shows that <i>V</i><sub>O</sub> occupies a site near the Cu impurity. The cumulative impact of Cu and <i>V</i><sub>O</sub> on structural and optical properties of the host m‑ZrO<sub>2</sub> is investigated. In comparison to pure ZrO<sub>2</sub>, the band gap of Cu-doped ZrO<sub>2</sub> with oxygen vacancies is reduced by 30%. The energy band gap reduction relates to the creation of spin-polarized gap states. This band gap reduction reduces the band gap of the doped system to the energy range in the visible region and thus increases its ability for absorption.
