Retraction: “Influence of electrode modification by Ar+ ion beam upon passivation and electrical characteristics in organic light-emitting diodes” [J. Mater. Res. 20, 81 (2005)]

This Journal of Materials Research article mainly contained essentially identical data, analyses, and conclusions that the authors had submitted and published in several other journals without notifying JMR or those journals. This is a strict departure from JMR policy: "Manuscripts are accepted with the understanding thai they represent original research, except for review articles, and that they have not been copyrighted, published, or submitted for publication elsewhere." The authors were asked to submit a formal letter of retraction, which has been received and is signed by all coauthors. This article has been removed from the MRS website.
