One item in a bibliographic list.
A <ref> is typically a citation describing a referenced work (see Tagging References). This Tag Set allows notes as well as citations in a bibliographic list, but best practice is to place notes in an <fn-group> or <notes> section and use <ref-list> only for bibliographic citations.
Common Practice: There is usually a number or other label preceding each citation, for example, [Lapeyre 2012], which a tagger may choose to preserve using the <label> element.
Incomplete References: Some journals identify successive bibliographic references by the same author or involving the same journal by omitting the duplicated portion of the reference and inserting a vertical rule or the word “Ibid” or “Id.” instead of the author’s name or the journal title. Since it is the intention of the Archiving and Interchange Tag Set to preserve the information provided in a bibliographic reference, and since best practice tagging would make each bibliographic reference accessible for CrossRef (and similar) queries, such references should be enhanced by tagging the author’s name or the journal title based on the name or title provided in the proceeding reference. At the discretion of the archive the word “Ibid” or “Id.” may also be retained as part of the textual content.

<p>While the samples appear homogeneous in terms of local variations in
transition energy and PL intensity, the response to external electric fields
is strongly inhomogeneous, which can most likely be attributed to local
variations in the AlGaN back contact conductivity as well as inhomogeneities
in the passivation process.</p>
