The macroscopic activation energy was determined indicating a conduction process by oxygen vacancies. 2022 artículo científico 0258-5995 https://www.redalyc.org/articulo.oa?id=443570155010 https://www.redalyc.org/journal/4435/443570155010/ https://www.redalyc.org/journal/4435/443570155010/html/ https://www.redalyc.org/journal/4435/443570155010/443570155010.epub https://www.redalyc.org/journal/4435/443570155010/movil en http://www.redalyc.org/revista.oa?id=4435 Revista Cubana de Química application/pdf Universidad de Oriente Revista Cubana de Química (Cuba) Num.1 Vol.34 |
