Is the AAP version of the article definitive?


No. This is an unedited version of a peer-reviewed manuscript that has been accepted for publication. The manuscript will undergo copyediting, typesetting and a proof review before it is published in its final form. During the production process errors may be discovered which could affect the content, and all legal disclaimers apply.
The paper does have a DOI (Digital Object Identifier) and therefore it can be referenced as soon as it appears on the Light: Science & Applications site.


What is the paper's official publication date?


For legal purposes (for example, establishing intellectual property rights), we assume that online publication constitutes public disclosure. But this is for the courts to decide; NPG's role as a publisher is to provide clear documentation of the publication history of a paper, both online and in print.


Must I subscribe to the journal in order to read AAP articles?


No. Access to AAP papers are free of charge.


How does AAP affect the calculation of Impact Factors?


Impact factors are calculated by Thomson Reuters (formerly ISI). At present, Thomson Reuters bases its calculations on the date of print publication alone, so until or unless Thomson Reuters changes its policy, AAP has no effect on Impact Factors.
See the Thomson Reuters site for a full explanation of how impact factors are calculated.


About Digital Object Identifiers


A digital object identifier (DOI) is an international, public, "persistent identifier of intellectual property entities" in the form of a combination of numbers and letters. For NPG content the DOI is assigned to an item of editorial content, providing a unique and persistent identifier for that item. The DOI system is administered by the International DOI Foundation, a not-for-profit organization. CrossRef, a not-for-profit organization, makes the DOI a reference linking standard and enables cross-publisher linking. It also maintains the lookup system for DOIs. NPG is a founding, and board, member of CrossRef.


Can I use the DOI in a reference citation?


Yes. Digital content may be referenced by providing the paper's DOI at the end of the citation. For example:

[Author(s)]. [Title]. Light: Science & Applications accepted article preview, [Year], [volume]; doi:[DOI].


How can I use a DOI to find a paper?


    To find a paper on the platform use the paper's DOI as a Search term.
    To resolve any DOI, go to the DOI System proxy server and enter the paper's DOI.
