<ref> Reference Item
One item in a bibliographic list.
Usage/Remarks
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 a <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, [Richardson 2015], 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 Journal 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>
