Scope of APEX

Subjects Covered by APEX

The journal publishes articles dealing with the applications of physical principles as well as articles concerning the understanding of physics with particular applications in mind. However as a letter journal, emphasis will be given to developing and emerging fields in applied physics. A work of high originality but concerning a field not in a competitive area may be suggested to be submitted to the JJAP Communication section. Examples of fields of current interest includes

  • Semiconductors, dielectrics, and organic materials
  • Photonics, quantum electronics, optics, and spectroscopy
  • Spintronics, superconductivity, and strongly correlated materials
  • Device physics including quantum information processing
  • Nanoscale science and technology
  • Crystal growth, surfaces, interfaces, thin films, and bulk materials
  • Plasmas, applied atomic and molecular physics, and applied nuclear physics
  • Device processing, fabrication and measurement technologies, and instrumentation
  • Cross-disciplinary areas such as bioelectronics/photonics, biosensing, environmental/energy technologies, and MEMS

  • The maximum length is three printed pages, including tables and figures (about 3000 words).
  • Abstract of no more than 100 words should be provided.
  • A Letter should not be divided into sections.
  • Full color printing for figures without extra charge.
  • Manuscripts should be written in clear and correct English. Manuscripts will be returned to the authors without review if the presentation of English is unacceptable. No English language correction services will be provided in the editorial process.

Comments and Replies

Citation Format

APEX uses a citation format based on six-digit article IDs instead of conventional page numbers.

The structure of the six-digit article ID is as follows:

  • first two digits indicate the issue number.
  • middle two digits indicate the article type and/or subject area.
    • 1n: Semiconductors, dielectrics, and organic materials
    • 2n: Photonics, quantum electronics, optics, and spectroscopy
    • 3n: Spintronics, superconductivity, and strongly correlated materials
    • 4n: Device physics (including quantum information processing)
    • 50-52: Nanoscale science and technology
    • 55-58: Crystal growth, surfaces, interfaces, thin films, and bulk materials
    • 60-64: Plasmas, applied atomic and molecular physics, and applied nuclear physics
    • 65-67: Device processing, fabrication and measurement technologies, and instrumentation
    • 7n: Cross-disciplinary areas (such as bioelectronics/photonics, biosensing, environmental/energy technologies, and MEMS*)
    • 91: Comments and Replies
    • 92: Errata
  • The last two digits are assigned according to publication order, within that issue and section.

An example of the correct citation format for an article in APEX is:

A. Oyo and B. Buturi: Appl. Phys. Express 1 (2008) 011001.

In the full-text PDF file available online and in the printed issue, the article ID appears on each printed page. A hyphen followed by a page number added consecutively is appended at the end of the article ID. For the sample article above, the printed pages would appear with this page numbering: 011001-1, 011001-2, and 011001-3. The hyphen and page numbers should not be used when citing or searching for an article.
